Question

Which expression would be easier to simplify if you used the associative property to change the grouping?

A. [(-) + (-)] +(-3)
B. 0.85+ (0.15 +(-3)
C. (160 + 40) +27
D. 1++(-+)]

Answer 1

The expression that would be easier to simplify using the associative property to change the grouping is option C: (160 + 40) + 27.

Step-by-step explanation:

The expression that would be easier to simplify using the associative property to change the grouping is option C: (160 + 40) + 27.

The associative property states that when adding or subtracting numbers, the grouping of the numbers does not matter. So, you can group the numbers in any way you like.

In this case, if we change the grouping to (160 + (40 + 27)), we can simplify it as follows:

1. Calculate the sum in the parentheses: 40 + 27 = 67
2. Substitute the sum back into the expression: 160 + 67
3. Calculate the final result: 160 + 67 = 227
