What expression would be easier to simplify if you use the associative property to change the grouping? A.[(-0.2)+(-0.6)]+1.7
B.(2+5/2)+(-1/2)
C.(60+40)+(-27)
D.6+[4/9+(-2/9)]

B

Step-by-step explanation:

2+5/2 is hard to add since first you have to make 2 into a fraction with the denominator 2. If you use the associative property, you can just easily combine -1/2 and 5/2 without any converting into fractions

c is the correct answer

step-by-step explanation:

the equivalent expression are always the hardest ones but you look at the gcf also
