Question

(a+b)+c=a+(b+c)
1) a=2/5,b=4/3,c=6/5

Answer 1

Answer:

2/5+4/3+6/5

Step-by-step explanation:

6+20+18/15=44/15

2/5+4/3+6/5=6+20+18/15=44/15

Answer 2

Step-by-step explanation:

To prove :(a+b) + c = a+(b+c)

Given : a=2/5 b=4/3 c=6/5

solution: LHS

(a+b) + c = ( 2/5 + 4/3) + 6/5

= ( 6+20/15 ) + 6/5

=26/15 + 6/5

= 26 + 18 / 15

= 44/15

RHS

a + (b+c) = 2/5 + ( 4/3 + 6/5)

= 2/5 + (20+18/15)

=2/5 + 38/15

= 6+ 38 / 15

= 44/15

● LHS=RHS
