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

2 × 10 × 7 = 7 × 10 × 2.

Step-by-step 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.
