All questions

Question 1

How do you write 731 in words? Use the same style as 542 written as five hundred forty-two.

  1. seven hundred thirty-one (correct answer)
  2. seven hundreds thirty-one
  3. seven hundred thirty one
  4. seven hundred and thirty-one
Explanation: Following the same style as five hundred forty-two, 731 is written as seven hundred thirty-one, using hundred (not hundreds) and a hyphen between thirty and one. Choice B incorrectly pluralizes hundred. Choice C leaves out the hyphen. Choice D adds the word and, which is not used in this style.

Question 2

What is 700+20+9700 + 20 + 9 in standard form?

  1. 709
  2. 792
  3. 7029
  4. 729 (correct answer)
Explanation: Combining 700, 20, and 9 in standard form gives 729. Choice A, 709, leaves out the tens place value. Choice B, 792, swaps the tens and ones digits. Choice C, 7029, comes from writing the numbers side by side instead of adding their place values together.

Question 3

A three-digit number has 4 hundreds, 2 tens, and 7 ones. How should this number be written in word form?

  1. four hundred twenty-seven (correct answer)
  2. four hundred two seven
  3. forty-two seven
  4. four hundred twenty seven ones
Explanation: 4 hundreds, 2 tens, and 7 ones make the number 427, written in words as four hundred twenty-seven. Choice B just lists the digits instead of using place-value words. Choice C drops the hundreds place entirely. Choice D incorrectly adds the word ones to the end.

Question 4

What is the standard form of 500+60+9500+60+9?

  1. 560
  2. 569 (correct answer)
  3. 506
  4. 596
Explanation: 500 + 60 + 9 combines 5 hundreds, 6 tens, and 9 ones to make 569. 560 leaves out the 9 ones. 506 leaves out the 6 tens. 596 swaps the tens and ones digits.

Question 5

Which shows 584 in word form?

  1. five hundred eighty-four (correct answer)
  2. five hundred forty-eight
  3. five thousand eighty-four
  4. five hundred eight
Explanation: 584 has 5 hundreds, 8 tens, and 4 ones, which is written in words as five hundred eighty-four (no 's' added to 'hundred'). Five hundred forty-eight swaps the tens and ones digits to read 548 instead of 584. Five thousand eighty-four mistakes the hundreds place for a thousands place. Five hundred eight leaves out the ones digit entirely.

Question 6

How do you write 417 in words?

  1. four hundred seventeen (correct answer)
  2. four hundred and seventeen
  3. four hundreds seventeen
  4. four hundred seventy-one
Explanation: Four hundred seventeen is correct because 417 has 4 hundreds, 1 ten, and 7 ones, written without the word 'and.' Four hundred and seventeen adds an unnecessary 'and,' which is not standard number-word form. Four hundreds seventeen incorrectly makes 'hundred' plural. Four hundred seventy-one swaps the tens and ones digits, naming the number 471 instead of 417.

Question 7

Which shows 631 in expanded form?

  1. 600+300+1600 + 300 + 1
  2. 60+30+160 + 30 + 1
  3. 6+3+16 + 3 + 1
  4. 600+30+1600 + 30 + 1 (correct answer)
Explanation: 631 in expanded form is 600+30+1600 + 30 + 1, since 631 has 6 hundreds, 3 tens, and 1 one. Choice A mistakenly treats the tens digit as another hundreds digit. Choice B treats the hundreds digit as if it were a tens digit. Choice C uses only the digits themselves instead of their place values.

Question 8

What is "two hundred forty-one" written as a number?

  1. 241 (correct answer)
  2. 214
  3. 2401
  4. 201
Explanation: The correct answer is 241, because 'two hundred forty-one' means 2 hundreds, 4 tens, and 1 one. Choice B (214) swaps the tens and ones digits. Choice C (2401) adds an extra digit that doesn't belong. Choice D (201) leaves out the tens place.

Question 9

How do you write 490 in words?

  1. four hundred ninety-zero
  2. four hundred ninety (correct answer)
  3. four hundred and ninety
  4. four hundreds ninety
Explanation: 490 is written as "four hundred ninety." Choice A ("four hundred ninety-zero") incorrectly reads the zero digit aloud as its own word. Choice C ("four hundred and ninety") adds the word "and," which isn't used in standard number names. Choice D ("four hundreds ninety") incorrectly pluralizes "hundred."

Question 10

What is the expanded form of 590?

  1. 5+9+05 + 9 + 0
  2. 500+90500 + 90 (correct answer)
  3. 500+9500 + 9
  4. 500+900500 + 900
Explanation: 590 has 5 hundreds and 9 tens with 0 ones, so its expanded form is 500+90500+90. 5+9+05+9+0 uses the digits themselves instead of their place values. 500+9500+9 leaves out the tens value entirely. 500+900500+900 mistakenly doubles the hundreds value.

Question 11

Which number shows "nine hundred twenty-four"?

  1. 902
  2. 9402
  3. 924 (correct answer)
  4. 942
Explanation: Nine hundred twenty-four is written as 924. Choice A is missing the twenty. Choice B adds an extra digit that doesn't belong. Choice D swaps the order of the last two digits.

Question 12

Which shows 568 in word form?

  1. five hundred sixty-eight (correct answer)
  2. five hundred and sixty-eight
  3. five hundreds sixty-eight
  4. five hundred sixty eight
Explanation: The standard word form of 568 is "five hundred sixty-eight," written without the word "and" and with a hyphen joining sixty and eight, so A is correct. Choice B incorrectly inserts the word "and," which is not used in standard American number names. Choice C incorrectly makes "hundred" plural. Choice D leaves out the hyphen that should join sixty and eight.

Question 13

A number written in expanded form is 300+5300 + 5. What is this same number when 4 tens are added to it?

  1. 700+5700 + 5
  2. 300+9300 + 9
  3. 300+40+5300 + 40 + 5 (correct answer)
  4. 300+54300 + 54
Explanation: Adding 4 tens to 300+5300 + 5 means adding 40, which gives 300+40+5300 + 40 + 5, so C is correct. A is wrong because it misreads 4 tens as 4 hundreds, giving 700 instead of 340. B is wrong because it adds only 4 ones instead of 4 tens. D is wrong because it combines the tens and ones digits together instead of keeping them separate.

Question 14

The digits 7, 0, and 3 are used to make a three-digit number: 7 hundreds, 0 tens, and 3 ones (seven hundred three). What is this number in expanded form, using only the place values that are not zero?

  1. 700+0+3700 + 0 + 3
  2. 700+30700 + 30
  3. 700+3700 + 3 (correct answer)
  4. 7+0+37 + 0 + 3
Explanation: Since there are 0 tens, the expanded form only needs the hundreds and ones place values: 700+3700 + 3. Choice A includes a zero term that the stem asks to leave out. Choice B mistakenly treats the ones digit as if it were in the tens place. Choice D uses the digits themselves instead of their actual place values.

Question 15

Emma writes the number four hundred six in expanded form. Then she adds 30 to that number. What is the new number in standard form?

  1. 466
  2. 406
  3. 430
  4. 436 (correct answer)
Explanation: The new number is 436, since 406 plus 30 equals 436. Choosing 466 would mean adding 60 instead of 30. Choosing 406 leaves out the addition of 30 entirely. Choosing 430 comes from adding 30 to only part of the number instead of the whole value.

Question 16

Look at the number line. Point M shows a number that can be written as 600+50+4600 + 50 + 4. If Point N is 20 more than Point M, how should Point N be written in word form?

  1. six hundred seventy-four (correct answer)
  2. six hundred fifty-four
  3. six hundred eighty-four
  4. six hundred sixty-four
Explanation: Point M is 600+50+4600 + 50 + 4, which is 654, and 20 more than 654 is 674, written as six hundred seventy-four, matching A. B is incorrect because it represents 654, the value of Point M, not Point N. C is incorrect because it represents 684, which is 30 more than Point M rather than 20 more. D is incorrect because it represents 664, which is only 10 more than Point M.

Question 17

What is 800+70+4800 + 70 + 4 in standard form?

  1. 874 (correct answer)
  2. 7074
  3. 844
  4. 784
Explanation: The correct answer is 874, because 800 + 70 + 4 combines the hundreds, tens, and ones into one number. Choice B (7074) strings the digits together instead of adding their place values. Choice C (844) swaps the ones and tens digits. Choice D (784) swaps the hundreds and tens digits.

Question 18

Write 860 in expanded form.

  1. 80+6080 + 60
  2. 8+6+08 + 6 + 0
  3. 800+6800 + 6
  4. 800+60800 + 60 (correct answer)
Explanation: In expanded form, 860 is written as the sum of its place values: 800+60800+60 (8 hundreds and 6 tens, with 0 ones). Choice A drops a zero from the hundreds place. Choice B lists single digits instead of place values. Choice C leaves out the tens place value.

Question 19

Which of these shows the same number written in three different forms: standard form, word form, and expanded form?

  1. 829829, eight hundred twenty-nine, 800+90+2800 + 90 + 2
  2. 892892, eight hundred ninety-two, 800+90+2800 + 90 + 2 (correct answer)
  3. 892892, eight hundred ninety-two, 800+20+9800 + 20 + 9
  4. 892892, eight hundred twenty-nine, 800+90+2800 + 90 + 2
Explanation: When you see a question asking about different forms of numbers, you need to check that the standard form (regular digits), word form (written out), and expanded form (broken into place values) all represent the exact same number. Let's examine choice B, which is correct: 892892, eight hundred ninety-two, 800+90+2800 + 90 + 2. The standard form shows 892892. The word form "eight hundred ninety-two" also represents 892892. The expanded form breaks down the place values: 800800 (8 hundreds) + 9090 (9 tens) + 22 (2 ones) = 892892. All three forms match perfectly. Now let's see why the other choices are wrong. Choice A has 829829 in standard form, but "eight hundred twenty-nine" in word form, and 800+90+2800 + 90 + 2 in expanded form. The expanded form actually equals 892892, not 829829, so the forms don't match. Choice C shows 892892 in standard form and "eight hundred ninety-two" in word form (both correct), but the expanded form 800+20+9800 + 20 + 9 equals 829829, not 892892. Choice D has 892892 in standard form, but "eight hundred twenty-nine" in word form, which represents 829829, creating a mismatch. When checking number forms, always verify each form independently, then confirm they all represent the same value. Pay special attention to the tens and ones places, as these are where most mistakes occur in expanded form.

Question 20

A mystery number has the same hundreds digit as 521, the same tens digit as 847, and the same ones digit as 193. What is this mystery number in word form?

  1. five hundred four three
  2. five hundred forty three
  3. five forty-three
  4. five hundred forty-three (correct answer)
Explanation: When you see a question about place value and digit positions, you need to carefully identify which digit goes in each place: hundreds, tens, and ones. Let's break down this mystery number step by step. First, find the hundreds digit from 521 - that's the 5. Next, find the tens digit from 847 - that's the 4. Finally, find the ones digit from 193 - that's the 3. So your mystery number is 543. Now you need to write 543 in word form. Five hundred represents the hundreds place, forty represents the tens place (remember that 40 is written as "forty," not "four zero"), and three represents the ones place. The complete word form is "five hundred forty-three." Looking at the wrong answers: Choice A says "five hundred four three," which incorrectly separates the tens and ones digits instead of combining them into "forty-three." Choice B writes "five hundred forty three" without the hyphen, but more importantly, many students might not notice this represents the same number as the correct answer - the key difference here is that B might be missing proper formatting that's expected in formal number writing. Choice C says "five forty-three," which leaves out the word "hundred" entirely, making it unclear and incorrect. Remember this strategy: when writing numbers in word form, always include "hundred" for the hundreds place, combine the tens and ones into compound numbers when appropriate (like "forty-three"), and double-check that each digit lands in the right place value position.
