Question

which expression would be easier to simplify if you use the associative property to change the grouping A: [-14+(-26)]+67B: (2/5+3/5) +7/3C: (43 + 60) + 40D: (50+50)+63

Answer 1

The associative property let us associate different terms or factors in order to solve some expression.

We have to find the expression in which this property is more useful.

The only expression where the associative may be helpful is C, as we can associate this way:

(43 + 60) + 40 = 43 + (60 + 40) = 43 + 100 = 143

In the other expression there is no advantage in applying this property.

Answer: C
