Question

verify that(a+b)+c=a+(b+c) by taking (a)= -2/3, b =5/6 and c = -5/8​

Answer 1

(a+b) +C=a+(b+C)

=(-2/3+5/6)+-5/8=-2/3+(5/6+-5/8)

=(-4+5/6)+-5/8=-2/3+(20+-15/24)

=1/6+-5/8=-2/3+5/24

=4+-15/24=-16+5/24

=-11/24=-11/24

Answer 2

Step-by-step explanation:

the sum went like this

in the statement they have given us

1. a =to minus 2 by 3 b is equal to minus 5 by 6 and c is equal to minus 5 by 8
2. in a question they said we have to use (a+b)+c.=(a+b)+c

Left hand side (a + b) + c

• (-⅔+⅚) + -⅝

15+(-12)/18-(-5/8)

• 3/18cut on table of ⅙= -5/8
• 1/6-5/8

8-30/48= -22/48= -11/
