All questions

Question 1

Carlos has 12 toy cars. Yuki has 3 times as many toy cars as Carlos. How many toy cars does Yuki have?

  1. 9 toy cars
  2. 15 toy cars
  3. 12 toy cars
  4. 36 toy cars (correct answer)
Explanation: Choice D is correct because Yuki has 3 times as many toy cars as Carlos, and 3 times 12 is 36. Choice A is incorrect because 9 is less than Carlos's own total, which does not match 3 times as many. Choice B is incorrect because it does not result from multiplying 12 by 3. Choice C is incorrect because it simply repeats Carlos's total instead of tripling it.

Question 2

Maya has 88 trading cards. Keisha has 44 times as many trading cards as Maya. How many trading cards does Keisha have?

  1. 32 trading cards (correct answer)
  2. 4 trading cards
  3. 12 trading cards
  4. 40 trading cards
Explanation: 32 trading cards is correct because 4×8=324 \times 8 = 32. 4 trading cards is incorrect because it uses only one of the two given numbers. 12 trading cards is incorrect because it results from adding instead of multiplying (8+4=128 + 4 = 12). 40 trading cards is incorrect because it results from multiplying by 5 instead of 4.

Question 3

Chen saved $48, which is 6 times as much as Amir saved. How much did Amir save?

  1. $8 (correct answer)
  2. $42
  3. $54
  4. $288
Explanation: This question tests 4th grade ability to multiply or divide to solve word problems involving multiplicative comparison, distinguishing multiplicative comparison from additive comparison (CCSS.4.OA.2). Multiplicative comparison uses 'times as many/much' language—'A is n times as many as B' means A = n × B, where A is the larger quantity (product), n is the multiplier (how many times), and B is the reference quantity (what's being multiplied). This is different from additive comparison ('A is n more than B' means A = B + n). To solve multiplicative comparisons: if finding the larger quantity (product), multiply; if finding how many times (multiplier) or the reference quantity, divide. This problem states Chen saved $48, which is 6 times as much as Amir saved, identifying $48 as the product, 6 as the multiplier, and asking for the reference quantity (Amir's savings), with the equation 48 = 6 × ? requiring division to solve. Choice A is correct because dividing the product by the multiplier, 48 ÷ 6 = 8, gives the reference quantity, demonstrating understanding of multiplicative comparison and choosing the correct operation. Choice C represents subtracting instead of dividing (48 - 6 = 42), which happens when students confuse the operations or misinterpret 'times as much' as an additive difference. To help students: Distinguish multiplicative from additive comparison—MULTIPLICATIVE: 'times as many/much' → multiply or divide; ADDITIVE: 'more than, less than' → add or subtract. For multiplicative problems, identify three parts: (1) Reference quantity, (2) Multiplier, (3) Product, then use Product = Multiplier × Reference, dividing product by multiplier if reference unknown; practice with bar models and language distinction to avoid confusing 'times as many' with 'more than.'

Question 4

A toy store has red, blue, and green bouncy balls. There are 48 red balls, which is 6 times as many as blue balls. The green balls number 3 times as many as blue balls. What is the total number of bouncy balls in the store?

  1. 56 total bouncy balls
  2. 72 total bouncy balls
  3. 80 total bouncy balls (correct answer)
  4. 104 total bouncy balls
Explanation: Blue balls: 48 ÷ 6 = 8 blue balls. Green balls: 8 × 3 = 24 green balls. Total: 48 + 8 + 24 = 80 balls. Choice A adds 48 + 8 only. Choice B adds 48 + 24 only. Choice D incorrectly calculates green balls as 48 + 8 = 56, then adds all incorrectly.

Question 5

A farmer has chickens and cows on his farm. He has 60 chickens, which is 5 times as many as the number of cows. Each cow produces 3 gallons of milk per day. If the farmer sells milk for $2 per gallon, how much money does he make from milk in one day?

  1. $36 from milk daily
  2. $72 from milk daily (correct answer)
  3. $120 from milk daily
  4. $360 from milk daily
Explanation: Number of cows: 60 ÷ 5 = 12 cows. Total milk: 12 × 3 = 36 gallons per day. Money earned: 36 × $2 = $72 per day. Choice A stops at the gallons amount. Choice C uses 60 × 2 incorrectly. Choice D uses 60 × 3 × 2 incorrectly.

Question 6

Keisha has 4545 shells. This is 55 times as many shells as Maya has. How many shells does Maya have?

  1. 50 shells
  2. 5 shells
  3. 40 shells
  4. 9 shells (correct answer)
Explanation: 9 shells is correct because 45÷5=945 \div 5 = 9. 50 shells is incorrect because it results from adding instead of dividing. 5 shells is incorrect because it matches the multiplier itself rather than the answer. 40 shells is incorrect because it results from subtracting instead of dividing.

Question 7

Sofia has 8 stickers. Jamal has 5 times as many stickers as Sofia. How many stickers does Jamal have?

  1. 45 stickers
  2. 13 stickers
  3. 40 stickers (correct answer)
  4. 8 stickers
Explanation: Jamal has 40 stickers because "times as many" means multiplying: 8 × 5 = 40. Choice B adds 8 + 5 instead, treating "times as many" like "more than." Choice A adds 5 extra onto the correct product. Choice D repeats Sofia's total instead of finding Jamal's.

Question 8

Emma has 7 marbles. Marcus has 49 marbles. Marcus has how many times as many marbles as Emma? Use the equation 49=?×749 = ? \times 7.

  1. 56 times as many
  2. 7 times as many (correct answer)
  3. 9 times as many
  4. 42 times as many
Explanation: This question tests 4th grade ability to multiply or divide to solve word problems involving multiplicative comparison, distinguishing multiplicative comparison from additive comparison (CCSS.4.OA.2). Multiplicative comparison uses 'times as many/much' language—'A is n times as many as B' means A = n × B, where A is the larger quantity (product), n is the multiplier (how many times), and B is the reference quantity (what's being multiplied). This is different from additive comparison ('A is n more than B' means A = B + n). To solve multiplicative comparisons: if finding the larger quantity (product), multiply; if finding how many times (multiplier) or the reference quantity, divide. This problem states Emma has 7 marbles and Marcus has 49 marbles, asking how many times as many Marcus has as Emma, identifying 49 as the product, 7 as the reference quantity, and asking for the multiplier, with the equation 49 = ? × 7 requiring division to solve. Choice B is correct because dividing product by reference: 49 ÷ 7 = 7 times as many, which demonstrates understanding of multiplicative comparison and choosing the correct operation. Choice A represents multiplying instead of dividing (7 × 6 = 42, perhaps miscounting), which happens when students divide in the wrong direction or confuse operations. To help students: Distinguish multiplicative from additive comparison. MULTIPLICATIVE: 'times as many/much' → multiply or divide. ADDITIVE: 'more than, less than' → add or subtract. For multiplicative problems, identify three parts: (1) Reference quantity (being compared to), (2) Multiplier (how many times), (3) Product (result). Then: Product = Multiplier × Reference. If product unknown → multiply. If multiplier unknown → divide product by reference. If reference unknown → divide product by multiplier. Use bar models: draw small bar for reference, large bar for product (n times as long), label multiplier. Compare: '5 times as many as 7' = 5 × 7 = 35, but '5 more than 7' = 7 + 5 = 12 (very different!). Practice distinguishing language. Watch for: confusing 'times as many' with 'more than,' using addition when should multiply, dividing wrong direction, and not identifying which quantity is unknown.

Question 9

Marcus ran 28 laps, which is 7 times as many laps as Emma ran. How many laps did Emma run?

  1. 4 laps (correct answer)
  2. 21 laps
  3. 7 laps
  4. 35 laps
Explanation: Since Marcus ran 7 times as many laps as Emma, dividing his total by 7 gives Emma's laps: 28 / 7 = 4. Choice C (7 laps) mistakes the multiplier itself for the answer. Choices B (21) and D (35) come from subtracting or adding instead of dividing.

Question 10

Carlos has 1010 toy cars. Yuki has 33 times as many toy cars as Carlos. How many toy cars does Yuki have?

  1. 13 toy cars
  2. 30 toy cars (correct answer)
  3. 7 toy cars
  4. 3 toy cars
Explanation: 30 toy cars is correct because 3×10=303 \times 10 = 30. 13 toy cars is incorrect because it results from adding instead of multiplying. 7 toy cars is incorrect because it results from subtracting instead of multiplying. 3 toy cars is incorrect because it matches the multiplier itself rather than the answer.

Question 11

Amir has 63 points in a game. Chen has 7 times as many points as Amir. How many points does Chen have?

  1. 9 points
  2. 441 points (correct answer)
  3. 70 points
  4. 56 points
Explanation: Chen has 7 times as many points as Amir, so 63 x 7 = 441 points. Choice A comes from dividing 63 by 7 instead of multiplying. Choice C is close to an estimate but does not reflect multiplying 63 by 7 correctly. Choice D reflects an incomplete multiplication rather than the full product.

Question 12

Jamal has 42 baseball cards. Sofia has 6 baseball cards. How many times as many baseball cards does Jamal have as Sofia?

  1. 48
  2. 36
  3. 7 (correct answer)
  4. 6
Explanation: The correct answer is C, 7, because 42 divided by 6 equals 7. Choice A, 48, comes from adding 42 and 6 instead of dividing. Choice B, 36, comes from subtracting 6 from 42 instead of dividing. Choice D, 6, simply restates Sofia's number of cards instead of comparing the two amounts.

Question 13

At a carnival, the Ferris wheel has 36 seats. This is 9 times as many seats as the bumper car ride. The roller coaster has 5 times as many seats as the bumper cars, but 12 of its seats are broken. How many working seats does the roller coaster have?

  1. 8 working roller coaster seats (correct answer)
  2. 15 working roller coaster seats
  3. 20 working roller coaster seats
  4. 32 working roller coaster seats
Explanation: The bumper cars have 36÷9=436 \div 9 = 4 seats. The roller coaster has 5×4=205 \times 4 = 20 seats, but 12 are broken, leaving 20−12=820 - 12 = 8 working seats. Choice B does not match any correct intermediate step. Choice C gives the roller coaster's total seats before subtracting the broken ones. Choice D uses an incorrect number of bumper car seats.

Question 14

A bakery sold 144 muffins on Saturday. They sold 6 times as many muffins as cookies on Saturday. On Sunday, they sold 4 times as many cookies as they sold on Saturday. How many cookies did they sell on Sunday?

  1. 24 cookies on Sunday
  2. 36 cookies on Sunday
  3. 96 cookies on Sunday (correct answer)
  4. 576 cookies on Sunday
Explanation: Saturday's cookie total equals 144 muffins divided by 6, which is 24 cookies. Sunday's cookies are 4 times that amount: 4 x 24 = 96. Choice A (24) stops after finding Saturday's total and forgets to multiply by 4. Choice D (576) multiplies the muffin count instead of the cookie count. Choice B (36) doesn't match either step of the correct calculation.

Question 15

Jake collected 56 baseball cards last month. This month he collected 7 times as many cards as his friend Sam collected this month. If Jake collected the same number this month as last month, how many cards did Sam collect this month?

  1. 7 baseball cards this month
  2. 8 baseball cards this month (correct answer)
  3. 49 baseball cards this month
  4. 63 baseball cards this month
Explanation: Jake collected 56 cards this month too, and that equals 7 times what Sam collected. Dividing 56 by 7 gives 8 cards for Sam. Choice C (49) subtracts 7 from 56 instead of dividing. Choice D (63) adds 7 to 56 instead of dividing. Choice A (7) mistakes the multiplier itself for the answer.

Question 16

Sofia has 3636 stickers. Jamal has 99 stickers. Sofia has how many times as many stickers as Jamal?

  1. 45 times as many
  2. 3 times as many
  3. 27 times as many
  4. 4 times as many (correct answer)
Explanation: 4 times as many is correct because 36÷9=436 \div 9 = 4. 45 times as many is incorrect because it results from adding instead of dividing. 3 times as many is incorrect because it does not match the actual quotient. 27 times as many is incorrect because it results from subtracting instead of dividing (36−9=2736 - 9 = 27).

Question 17

A movie theater has 3 screens. Screen 1 has 120 seats. Screen 2 has 4 times as many seats as Screen 3. Screen 1 has 2 times as many seats as Screen 3. If all screens are completely full for a show, how many people are watching movies total?

  1. 300 people watching movies
  2. 360 people watching movies
  3. 480 people watching movies
  4. 420 people watching movies (correct answer)
Explanation: Since Screen 1 has 2 times as many seats as Screen 3, Screen 3 has 120 / 2 = 60 seats. Screen 2 has 4 times as many seats as Screen 3, or 4 x 60 = 240 seats. Adding all three screens gives 120 + 60 + 240 = 420 people. Choices A, B, and C come from mixing up which screen the multipliers apply to.

Question 18

Sofia read 32 pages, which is 4 times as many pages as Jamal read. How many pages did Jamal read?

  1. 4 pages
  2. 128 pages
  3. 28 pages
  4. 8 pages (correct answer)
Explanation: Since Sofia read 4 times as many pages as Jamal, 32÷4=832 \div 4 = 8 pages is what Jamal read. Choice A is far too small. Choice B comes from multiplying instead of dividing (32×432 \times 4). Choice C comes from subtracting instead of dividing (32−432 - 4).

Question 19

Emma ran 27 laps, which is 3 times as many laps as Marcus ran. How many laps did Marcus run?

  1. 9 laps (correct answer)
  2. 3 laps
  3. 81 laps
  4. 24 laps
Explanation: The correct answer is A, 9 laps. Since Emma's 27 laps are 3 times as many as Marcus ran, dividing gives 27 divided by 3 equals 9. Choice B, 3 laps, comes from dividing by 9 instead of 3. Choice C, 81 laps, comes from multiplying 27 by 3 instead of dividing. Choice D, 24 laps, comes from subtracting 3 from 27 instead of dividing.

Question 20

Emma ran 27 laps. Marcus ran 9 laps. Emma ran how many times as many laps as Marcus?

  1. 18
  2. 3 (correct answer)
  3. 36
  4. 2
Explanation: Dividing Emma's laps by Marcus's laps gives 27 divided by 9, which equals 3, so Emma ran 3 times as many laps. Choice A reflects a subtraction-based comparison rather than division. Choice C reflects a multiplication error rather than division. Choice D is close but does not match the exact quotient of 27 divided by 9.
