Question

Find (a+b)/(a-b) if a=1/2, b=2/3?

Answer 1

Answer:

-7/36

Step-by-step explanation:

(a+b)/(a-b)

Substituting the value,

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

=7/6×-1/6

=-7/36

Answer 2

a+b = 1/2 + 2/3

= 3/6 + 4/6 ...(by LCM)

= 7/6 .... (1)

a-b = 1/2 - 2/3

= 3/6 - 4/6

= -1/6 ....(2)

Now, (a+b)/(a-b) = 7/6÷ -1/6 (from 1 and 2)

= 7/6 ❌ -6/1

= -7/1 (six gets divided)

= -7

FINAL ANSWER: -7
