Answer 2

I used associative property  and the product of 20 x 9 x 5 is 900.

What is associative property?

"The associative property states that when an expression has three terms, they can be grouped in any way to solve that expression. The grouping of numbers will never change the result of their operation. The associative property is true for the cases of addition and multiplication. Neither the sum nor the product of the expression changes."

For the given product of 20 x 9 x 5

I am using the associative property.

(20 x 9) x 5 = 900

First multiply 20 x 9, which gives 180

(180) x 5 = 900

Next multiply 180 x 5, which gives 900.

Hence, I used associative property  and the product of 20 x 9 x 5 is 900.
