  1. A student says that 0.5 is greater than 0.50. Is the student correct?

    Answer: No, 0.5 and 0.50 are equal in value

    Trailing zeros after a decimal point do not change the value, so 0.5 = 0.50.

  2. Which of the following represents the number 4,207 in expanded form?

    Answer: 4,000 + 200 + 7

    4,207 = 4,000 + 200 + 7, reflecting the thousands, hundreds, tens, and ones places.

  3. What is the remainder when 58 is divided by 7?

    Answer: 4

    7 × 8 = 56, and 58 − 56 = 2, so the remainder is 2.

  4. A classroom has 144 crayons to be shared equally among 12 students. How many crayons does each student get?

    Answer: 12

    144 ÷ 12 = 12 crayons per student.

  5. Which number is a composite number?

    Answer: 15

    15 is composite because it has factors other than 1 and itself (3 × 5 = 15).

  6. Round 3,846 to the nearest hundred.

    Answer: 3,800

    The tens digit is 4 (less than 5), so 3,846 rounds down to 3,800.

  7. Which expression shows the commutative property of addition?

    Answer: 2 + 3 = 3 + 2

    The commutative property states that changing the order of addends does not change the sum: a + b = b + a.

  8. What is the least common multiple (LCM) of 4 and 6?

    Answer: 12

    The multiples of 4 are 4, 8, 12… and of 6 are 6, 12…, so the LCM is 12.

  9. A number is multiplied by 0. What is the result?

    Answer: 0

    Any number multiplied by 0 equals 0, by the zero property of multiplication.

  10. Which of the following is an example of an even number?

    Answer: 64

    64 is even because it is divisible by 2 with no remainder.

  11. Estimate the sum of 389 + 214 by rounding each number to the nearest hundred.

    Answer: 600

    389 rounds to 400 and 214 rounds to 200; 400 + 200 = 600.

  12. What is the value of the digit 6 in the number 76,432?

    Answer: 6,000

    The digit 6 is in the thousands place, so its value is 6 × 1,000 = 6,000.

  13. A store sells apples in bags of 8. If a teacher needs 56 apples, how many bags must she buy?

    Answer: 7

    56 ÷ 8 = 7, so the teacher needs to buy 7 bags.

  14. Which of the following correctly orders these numbers from least to greatest: 0.6, 0.06, 0.66, 0.606?

    Answer: 0.06, 0.6, 0.606, 0.66

    Converting to thousandths: 0.060, 0.600, 0.606, 0.660 — ordering from least gives 0.06, 0.6, 0.606, 0.66.
