Answer + Step-by-step explanation:

10 × 5 × 2

= 10 × (5 × 2)   (associative property)

Hello there! Kaley originally solves by using (10 x 5) x 2 to result in 100 as the final answer. That being said, we can place the parenthesis in another place to identify another way Kaley can solve this problem:

10 x 5 x 2

= 10 x (5 x 2)

= 10 x 10

= 100

By placing the parenthesis in another place, what we did was simplify what 5 x 2 gave us and then multiply that by the remaining integer. Because 5 x 2 = 10, we can multiply 10 x 10 to find that:

1. 10 x 10 = 100

2. (10 x 5) x 2 = 10 x (5 x 2)

Likewise, if we wanted to, we could also rearrange the parenthesis to multiply 10 x 2 and get 20 x 5. That also would give us 100.

The other method to solve this problem is 10 x (5 x 2) = 100. If you need any extra help, let me know and I will gladly assist you.
