Question

(a+b)+c = a+(b+c)

a = 2/9
b = -3/2
c = 1/8​

Answer 1

Answer: -83/72 = -83/72 So both sides are equal.

Step-by-step explanation:

(a+b)+c = a+(b+c)

(2/9-3/2) + 1/8 = 2/9 + (-3/2 + 1/8)

Simplify  

(2/9 - 3/2) + 1/8

2/9-3/2+1/8

2/9 - 3/2 = -23/18

-23/18 + 1/8 = -83/72

LCM of 72 = 9,2,8

16/72 - 108/72 + 9/72

16 - 108 + 9/72 = -83/72

-83/72 = -83/72
