Which of the following is an example of the associative property of multiplication?

A. 7 · (3 + 5) = 21 + 35
B. 7 · (3 · 5) = (7 · 3) · 5
C. 7 · (3 · 5) = 7 · (5 · 3)
D. 7 · 1/7 = 1

Answered by admin @ 26/11/2021

Answer:

B. 7 · (3 · 5) = (7 · 3) · 5

Explanation:

The Associative Property of Multiplication states that with the use of GROUPING SYMBOLS, no matter how you write your numbers out\in-side them, you will ALWAYS get the exact same result. Although answer choice C looks close, they have parentheses wrapped around the EXACT SAME NUMBERS. They just reversed the order of how they were originally. This is what is known as the Commutative Property of Multiplication.
