All questions

Question 1

Which equation correctly represents the comparison "32 is 4 times as many as 8"?

  1. 32=4×832 = 4 \times 8 (correct answer)
  2. 32=8−432 = 8 - 4
  3. 8=4×328 = 4 \times 32
  4. 32=4+832 = 4 + 8
Explanation: The correct answer is A. The comparison states that 32 is 4 times as many as 8, which matches the equation 32 = 4 × 8. Choice B uses subtraction instead of multiplication to relate the numbers. Choice C reverses which number is being compared to which. Choice D uses addition instead of multiplication.

Question 2

Which equation correctly represents the comparison "42 is 6 times as many as 7"?

  1. 7=6×427 = 6 \times 42
  2. 42=6×742 = 6 \times 7 (correct answer)
  3. 42=7−642 = 7 - 6
  4. 42=6+742 = 6 + 7
Explanation: The comparison 42 is 6 times as many as 7 is correctly written as 42 = 6 x 7. Choice A reverses the equation, putting the smaller number on the side that should show the product. Choice C uses subtraction, which does not represent a times-as-many comparison. Choice D uses addition, which also does not represent a multiplicative comparison.

Question 3

Marcus saved $27. This is 9 times as much as Yuki saved. Which equation shows this comparison?

  1. 27=9×327 = 9 \times 3 (correct answer)
  2. 27=3−927 = 3 - 9
  3. 27=9+327 = 9 + 3
  4. 3=9×273 = 9 \times 27
Explanation: Choice A is correct because Marcus saved 27 dollars, which is 9 times as much as Yuki's 3 dollars, so 27 equals 9 times 3. Choice B is incorrect because it uses subtraction instead of multiplication to relate the two amounts. Choice C is incorrect because it uses addition instead of multiplication. Choice D is incorrect because it reverses which amount is being multiplied by 9.

Question 4

Maya says, "16 is 2 times as many as 8." Which equation represents her comparison?

  1. 16=2×816 = 2 \times 8 (correct answer)
  2. 16=8−216 = 8 - 2
  3. 8=2×168 = 2 \times 16
  4. 16=2+816 = 2 + 8
Explanation: This question tests 4th grade ability to interpret a multiplication equation as a comparison, understanding statements like '35 is 5 times as many as 7' and representing them as multiplication equations (CCSS.4.OA.1). Multiplication can represent a comparison between two quantities—'A is B times as many as C' means A = B × C, where A is the product (larger quantity), B is the multiplier (how many times), and C is the reference (smaller quantity being compared to). Because of the commutative property, the same equation can have two comparison interpretations: 35 = 5 × 7 means '35 is 5 times as many as 7' AND '35 is 7 times as many as 5' (both correct). The statement '16 is 2 times as many as 8' identifies 16 as the product, 2 as the multiplier, and 8 as the reference, giving the equation 16 = 2 × 8. Choice A is correct because it correctly writes the equation with product on left and factors multiplied on right, using proper comparison language 'times as many as.' This demonstrates understanding that multiplication equations represent comparisons, not just repeated addition. Choice B represents using addition instead of multiplication, which happens when students make arithmetic errors or don't recognize the comparison structure. To help students: Identify roles in statements and build equations; use bar models for visualization; practice both interpretations and distinguish from repeated addition, watching for backwards equations.

Question 5

What does the equation 18=6×318 = 6 \times 3 mean as a comparison statement?

  1. 6 is 18 times as many as 3.
  2. 3 is 6 times as many as 18.
  3. 3 is 18 times as many as 6.
  4. 18 is 6 times as many as 3. (correct answer)
Explanation: The equation shows that 6 groups of 3 equal 18, so 18 is 6 times as many as 3. Choice A swaps which number is being multiplied, incorrectly claiming 6 is 18 times as many as 3. Choice B reverses the relationship entirely, treating 3 as if it were 6 times as many as 18. Choice C also swaps the comparison direction, describing 3 as 18 times as many as 6. Only Choice D correctly matches the equation's structure: 18 is 6 times as many as 3.

Question 6

Interpret the equation 24=3×824 = 3 \times 8 as a comparison statement using "times as many."

  1. 24 is 3 times as many as 8. (correct answer)
  2. 8 is 24 times as many as 3.
  3. 3 is 24 times as many as 8.
  4. 24 is 3 more than 8.
Explanation: Choice A is correct because the equation 24 = 3 x 8 means 24 is 3 times as many as 8. Choice B is incorrect because it reverses the comparison, making 8 the larger group instead of 24. Choice C is incorrect because it also reverses which number is being compared to which. Choice D is incorrect because it describes an addition relationship, not the multiplication relationship shown in the equation.

Question 7

A parking lot has 3 sections. Section A has 15 cars. Section B has 4 times as many cars as Section A. Section C has 2 times as many cars as Section A.

Which equation shows how many times as many cars are in Section B compared to Section C?

  1. 60=2×3060 = 2 \times 30 (correct answer)
  2. 60=4×1560 = 4 \times 15
  3. 90=3×3090 = 3 \times 30
  4. 105=7×15105 = 7 \times 15
Explanation: Section B has 4×15=604 \times 15 = 60 cars, and Section C has 2×15=302 \times 15 = 30 cars. Since 60÷30=260 \div 30 = 2, Section B has 2 times as many cars as Section C, so 60=2×3060 = 2 \times 30. Choice B gives the number of cars in Section B compared to Section A, not Section C. Choices C and D use totals that don't match either section's actual car count.

Question 8

The local library tracks book borrowing by different age groups. In March, teenagers borrowed 56 books. Adults borrowed 7 times as many books as teenagers. Children borrowed half as many books as teenagers.

Which equation shows how many times as many books adults borrowed as children borrowed?

  1. 392=14×28392 = 14 \times 28 (correct answer)
  2. 392=7×56392 = 7 \times 56
  3. 364=13×28364 = 13 \times 28
  4. 420=15×28420 = 15 \times 28
Explanation: Adults borrowed 7×56=3927 \times 56 = 392 books, and children borrowed 56÷2=2856 \div 2 = 28 books. Since 392÷28=14392 \div 28 = 14, adults borrowed 14 times as many books as children, so 392=14×28392 = 14 \times 28. Choice B compares adults to teenagers rather than to children. Choices C and D use incorrect totals for the number of books adults borrowed.

Question 9

Roberto says "36 is 6 times as many as 6." Elena says "This is wrong because 36 divided by 6 equals 6, so 36 is 6 times as many as 6." What is the error in Elena's reasoning?

  1. Elena confused addition with multiplication in her explanation of the error
  2. Elena incorrectly calculated 6 times 6 as 36 instead of 30
  3. Elena should have said 36 is 1 time as many as 36, not 6 times as many
  4. Elena's correction says the same thing as Roberto's original statement (correct answer)
Explanation: The correct answer is D because Elena's own math, 36÷6=636 \div 6 = 6, confirms that 36 is 6 times as many as 6, the exact same claim Roberto made. She calls his statement wrong, but her reasoning actually proves he was right. Choice A is incorrect since there's no addition-versus-multiplication confusion here. Choice B is incorrect because 6×6=366 \times 6 = 36 is true, not a calculation error. Choice C describes a different, unrelated statement that Elena never made.

Question 10

The equation 32=4×832 = 4 \times 8 means that 32 is how many times as many as 8?

  1. 32 times
  2. 2 times
  3. 4 times (correct answer)
  4. 8 times
Explanation: Since 32=4×832 = 4 \times 8, dividing 32 by 8 shows that 32 is 4 times as many as 8. Choice A simply repeats the given total instead of finding the multiplier. Choice B could come from dividing 8 by 4 instead of 32 by 8, reversing the operation. Choice D mixes up the multiplier with the number being multiplied. Choice C correctly identifies 4 as the number of times as many.

Question 11

Sofia has 24 stickers. This is 3 times as many as Jamal has. Which equation matches the comparison?

  1. 8=3×248 = 3 \times 24
  2. 24=3×824 = 3 \times 8 (correct answer)
  3. 24=8−324 = 8 - 3
  4. 24=3+824 = 3 + 8
Explanation: Since Sofia has 3 times as many stickers as Jamal, and Sofia has 24, the comparison is 24 equals 3 times 8, making Choice B correct. Choice A reverses the relationship, placing the smaller number, 8, on the side that should show the product, and the larger number, 24, as if it were a factor. Choice C uses subtraction instead of multiplication, which does not represent a "times as many" comparison. Choice D uses addition instead of multiplication, which also does not represent the comparison correctly. A "times as many" comparison is shown with multiplication, not addition or subtraction.

Question 12

Sofia has 35 stickers. This is 5 times as many as Jamal has. Which equation matches this comparison?

  1. 35=5+735 = 5 + 7
  2. 7=5×357 = 5 \times 35
  3. 35=5×735 = 5 \times 7 (correct answer)
  4. 35=7−535 = 7 - 5
Explanation: Since Sofia's 35 stickers equal 5 times Jamal's amount, Jamal must have 7 stickers, and 35=5×735 = 5 \times 7 shows that relationship correctly. Choice A uses addition instead of multiplication, which doesn't represent a 'times as many' comparison. Choice B reverses which number is the total and which is the multiplier. Choice D uses subtraction, which doesn't capture a multiplicative comparison at all. Choice C is the only equation that correctly models Sofia having 5 times as many stickers as Jamal.

Question 13

The equation 56=7×856 = 7 \times 8 can be interpreted in two ways. Which pair of statements is correct?

  1. 8 is 7 times as many as 56, and 7 is 8 times as many as 56.
  2. 7 is 56 times as many as 8, and 8 is 56 times as many as 7.
  3. 56 is 7 times as many as 8, and 8 is 7 times as many as 56.
  4. 56 is 7 times as many as 8, and 56 is 8 times as many as 7. (correct answer)
Explanation: The equation means that 56 is 7 times as many as 8, and equivalently, 56 is 8 times as many as 7, since both statements describe the same multiplication viewed from different starting numbers. Choice A reverses the relationship, treating the smaller numbers as multiples of 56. Choice B swaps which number is being multiplied, making 56 the multiplier instead of the product. Choice C states the first part correctly but incorrectly claims 8 is 7 times as many as 56 for the second part. Choice D is the only option where both statements accurately reflect the equation.

Question 14

The equation 35=5×735 = 5 \times 7 can be interpreted in two ways. Which pair of statements both describe it?

  1. 35 is 5 times as many as 7, and 35 is 7 times as many as 5. (correct answer)
  2. 35 is 5 times as many as 7, and 7 is 35 times as many as 5.
  3. 35 is 5 plus 7, and 35 is 7 plus 5.
  4. 35 is 5 times as many as 35, and 35 is 7 times as many as 35.
Explanation: This question tests 4th grade ability to interpret a multiplication equation as a comparison, understanding statements like '35 is 5 times as many as 7' and representing them as multiplication equations (CCSS.4.OA.1). Multiplication can represent a comparison between two quantities—'A is B times as many as C' means A = B × C, where A is the product (larger quantity), B is the multiplier (how many times), and C is the reference (smaller quantity being compared to). Because of the commutative property, the same equation can have two comparison interpretations: 35 = 5 × 7 means '35 is 5 times as many as 7' AND '35 is 7 times as many as 5' (both correct). The equation 35 = 5 × 7 describes how 35 compares to 5 and to 7: 35 is 5 times as many as 7, or alternatively, 35 is 7 times as many as 5. Choice A is correct because it correctly identifies both valid interpretations using proper comparison language 'times as many as'; this demonstrates understanding that multiplication equations represent comparisons, not just repeated addition. Choice B represents mixed up product and factor roles in the second statement, which happens when students confuse which quantity is being compared (product) vs compared to (reference). To help students: Identify roles—Product (the amount being described, larger), Multiplier (how many times), Reference (the amount being compared to, smaller); pattern: 'Product is Multiplier times as many as Reference' → Product = Multiplier × Reference; use bar models: draw Reference bar, then Product bar that is Multiplier times as long; practice both directions: from equation to statement AND statement to equation; recognize both interpretations: 35 = 5 × 7 means BOTH '35 is 5 times as many as 7' AND '35 is 7 times as many as 5' (commutative property); connect to contexts: 'Sofia has 35 stickers, 5 times as many as Jamal's 7 stickers' → 35 = 5 × 7; distinguish from repeated addition: 'times as many as' signals comparison (35 compared to 7), while '5 groups of 7' signals repeated addition (though same equation); watch for: mixing up product and factors, using addition, forgetting 'as many as' wording, writing equation backwards, and not recognizing both valid interpretations.

Question 15

The equation 56=7×856 = 7 \times 8 can be interpreted in two ways. Which pair of statements both describe it?

  1. 56 is 7 times as many as 8, and 56 is 8 times as many as 7. (correct answer)
  2. 56 is 7 times as many as 7, and 56 is 8 times as many as 8.
  3. 7 is 56 times as many as 8, and 8 is 56 times as many as 7.
  4. 56 is 7 plus 8, and 56 is 8 plus 7.
Explanation: Choice A is correct because the equation 56 = 7 x 8 can be read as 56 is 7 times as many as 8, and also as 56 is 8 times as many as 7. Choice B is incorrect because it compares 7 to itself and 8 to itself instead of comparing 56 to each factor. Choice C is incorrect because it reverses which numbers are being compared. Choice D is incorrect because it uses addition instead of multiplication to describe the relationship.

Question 16

Which statement correctly interprets the equation 63=9×763 = 9 \times 7 using "times as many"?

  1. 63 is 9 plus as many as 7.
  2. 63 is 9 times as many as 7. (correct answer)
  3. 9 is 63 times as many as 7.
  4. 7 is 63 times as many as 9.
Explanation: The equation 63=9×763 = 9 \times 7 means 63 is 9 times as many as 7. Choice A uses "plus" instead of "times," which does not match multiplication. Choice C reverses the relationship, incorrectly treating 9 as the larger quantity. Choice D swaps which number is being compared to which.

Question 17

What does the equation 36=9×436 = 9 \times 4 mean as a comparison statement?

  1. 36 is 9 plus 4.
  2. 4 is 36 times as many as 9.
  3. 9 is 36 times as many as 4.
  4. 36 is 9 times as many as 4. (correct answer)
Explanation: Choice D is correct because the equation 36 = 9 x 4 means 36 is 9 times as many as 4. Choice A is incorrect because it describes an addition relationship instead of multiplication. Choice B is incorrect because it reverses which numbers are being compared. Choice C is incorrect because it also reverses which number is the times as many amount.

Question 18

Keisha has 32 beads. This is 4 times as many as Carlos has. Which equation matches the comparison?

  1. 32=4×832 = 4 \times 8 (correct answer)
  2. 32=4+832 = 4 + 8
  3. 8=4×328 = 4 \times 32
  4. 32=8−432 = 8 - 4
Explanation: Since Keisha's 32 beads equal 4 times Carlos's amount, Carlos must have 8 beads, and 32=4×832 = 4 \times 8 shows that relationship correctly. Choice B uses addition instead of multiplication, which doesn't represent a 'times as many' comparison. Choice C reverses which number is the total and which is the multiplier. Choice D uses subtraction, which doesn't capture a multiplicative comparison at all. Choice A is the only equation that correctly models Keisha having 4 times as many beads as Carlos.

Question 19

Lisa writes the equation 84=12×784 = 12 \times 7. She says this means "84 is 12 times as many as 7." Her friend Marcus says it means "84 is 7 times as many as 12." Who is correct?

  1. Only Lisa is correct
  2. Only Marcus is correct
  3. Both Lisa and Marcus are correct (correct answer)
  4. Neither is correct
Explanation: Both Lisa and Marcus are correct because a multiplication comparison can be read either way: 84 is 12 times as many as 7, and 84 is also 7 times as many as 12. Only Lisa is correct is incomplete because Marcus's statement is also true. Only Marcus is correct is incomplete for the same reason. Neither is correct is wrong because both statements correctly describe the equation.

Question 20

What does 28=4×728 = 4 \times 7 mean? Choose the correct comparison statement.

  1. 4 is 28 times as many as 7.
  2. 28 is 4 times as many as 7. (correct answer)
  3. 28 is 4 plus 7.
  4. 7 is 4 times as many as 28.
Explanation: This question tests 4th grade ability to interpret a multiplication equation as a comparison, understanding statements like '35 is 5 times as many as 7' and representing them as multiplication equations (CCSS.4.OA.1). Multiplication can represent a comparison between two quantities—'A is B times as many as C' means A = B × C, where A is the product (larger quantity), B is the multiplier (how many times), and C is the reference (smaller quantity being compared to). Because of the commutative property, the same equation can have two comparison interpretations: 35 = 5 × 7 means '35 is 5 times as many as 7' AND '35 is 7 times as many as 5' (both correct). The equation 28 = 4 × 7 describes how 28 compares to 4 and to 7: 28 is 4 times as many as 7, or alternatively, 28 is 7 times as many as 4. Choice B is correct because it correctly identifies the product (28), multiplier (4), and reference (7) in the comparison statement, using proper comparison language 'times as many as'; this demonstrates understanding that multiplication equations represent comparisons, not just repeated addition. Choice A represents mixed up product and factor roles, which happens when students confuse which quantity is being compared (product) vs compared to (reference). To help students: Identify roles—Product (the amount being described, larger), Multiplier (how many times), Reference (the amount being compared to, smaller); pattern: 'Product is Multiplier times as many as Reference' → Product = Multiplier × Reference; use bar models: draw Reference bar, then Product bar that is Multiplier times as long; practice both directions: from equation to statement AND statement to equation; recognize both interpretations: 35 = 5 × 7 means BOTH '35 is 5 times as many as 7' AND '35 is 7 times as many as 5' (commutative property); connect to contexts: 'Sofia has 35 stickers, 5 times as many as Jamal's 7 stickers' → 35 = 5 × 7; distinguish from repeated addition: 'times as many as' signals comparison (35 compared to 7), while '5 groups of 7' signals repeated addition (though same equation); watch for: mixing up product and factors, using addition, forgetting 'as many as' wording, writing equation backwards, and not recognizing both valid interpretations.
