ParaPro Number Sense and Basic Operations — Questions and Answers

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

Yes, because 0.5 has fewer digits
No, 0.5 and 0.50 are equal in value (Correct answer)
Yes, because 0.50 has an extra zero making it larger
No, 0.50 is greater because it has more digits

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.

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

4,000 + 200 + 7 (Correct answer)
4,000 + 20 + 7
400 + 200 + 7
4,000 + 207

Correct answer: 4,000 + 200 + 7

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

Question 3: What is the remainder when 58 is divided by 7?

1
2
3
4 (Correct answer)

Correct answer: 4

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

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

10
11
12 (Correct answer)
13

Correct answer: 12

144 ÷ 12 = 12 crayons per student.

Question 5: Which number is a composite number?

11
13
15 (Correct answer)
17

Correct answer: 15

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

Question 6: Round 3,846 to the nearest hundred.

3,800 (Correct answer)
3,900
4,000
3,850

Correct answer: 3,800

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

Question 7: Which expression shows the commutative property of addition?

(2 + 3) + 4 = 2 + (3 + 4)
2 + 3 = 3 + 2 (Correct answer)
2 + 0 = 2
2 × (3 + 4) = 2×3 + 2×4

Correct answer: 2 + 3 = 3 + 2

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

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

8
10
12 (Correct answer)
24

Correct answer: 12

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

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

The number itself
1
0 (Correct answer)
Undefined

Correct answer: 0

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

Question 10: Which of the following is an example of an even number?

37
41
53
64 (Correct answer)

Correct answer: 64

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

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

500
600 (Correct answer)
700
400

Correct answer: 600

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

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

6
600
6,000 (Correct answer)
60,000

Correct answer: 6,000

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

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

5
6
7 (Correct answer)
8

Correct answer: 7

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

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

0.06, 0.6, 0.606, 0.66 (Correct answer)
0.6, 0.06, 0.606, 0.66
0.06, 0.606, 0.6, 0.66
0.66, 0.606, 0.6, 0.06

Correct 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.
