Question

Which of the following demonstrates the commutative property across multiplication for 2 × 10 × 7

Answer 1

10*7*2 would be one answer, the commutative property states that a+b = b+a, meaning that no matter what order the numbers are in it still equals the same thing

Answer 2

2 × 10 × 7 = 7 × 10 × 2.

Explanation:

Given : 2 × 10 × 7

To find : Which of the following demonstrates the commutative property across multiplication.

Solution : We have given 2 × 10 × 7

By the commutative multiplication property : a × b × c = c× b × a.

Example : 1 * 3 * 5 = 5 *3 *1

15 = 15.

So, 2 × 10 × 7 = 7 × 10 × 2.

140 = 140

Therefore, 2 × 10 × 7 = 7 × 10 × 2.
