• Q8

Which states the commutative property of multiplication?

The numbers can be grouped in any order.

• Q9

Which of the following statements illustrate the distributive property?

2(3) = 3(2)

(3 +2) + 4 = 3 + (2 + 4)

3(2 + 4) = 3(2) + 3(4)

2 + 3 = 3 + 2

30s
• Q10

Which statement justifies that the associative property is not true for subtraction?

15 – 9 – 6 ≠ 6 – 9 – 15

15 – 9 ≠ 9 – 15

(15 – 9) – 6 ≠ 15 – (9 – 6)

15 – (9 – 6) ≠ (15 – 9) – (15 – 6)

30s
• Q11

Which of the following shows the Closure Property of addition for the set of integers?

8 ∙ 9 = 72

5 + 82 = 87

(6 + 7) + 8 = 13 + 8

(5 + 6) + 7 = 5 + (6 + 7)

30s
• Q12

Which of the following shows the correct use of the distributive property?

4(6 + 7) = (4 + 6) ∙ (6 + 7)

4(6 + 7) = (4 + 6) ∙ (4 + 7)

4(6 + 7) = 4(6) + 4(7)

4(6 + 7) = (4∙ 6) + 7
