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

A. 85 + (120 + 80)

B. [-40 + (60)] + 52

Answer 2

C

Explanation:

In A and B, the numbers involved in expressions are integers.

Hence, they can be easily added or subtracted.

In C, the numbers involved in expression are fractions which are not grouped together.

They can be added but by using associative property, it becomes much more easier.

That is, grouping fractions.
