Question

Q.1).(1).how to solve I don't know I try it but answer didn't came plz help me.

Answer 1

Since a/b = 5/6

Hence a = 5/6*b = 5b/6.

1. a+b / b

= 5b/6 + b / b

= 11b/6 / b

= 11/6.

2. a+b/a-b

= 5b/6 + b / 5b/6 - b

= 11b/6 / - b/6

= - 11.

Hope it's helpful to u.

Answer 2

here it is given that, a/b=5/6
(i) (a+b)/b
=>a/b+b/b
=>(5/6)+1
=>(5+6)/6
=>[11/6] ans.

(ii) a/b=5/6
=>a=5b/6
.: (a+b)/(a-b)
=>(a/a-b)+(b/a-b)
=>[(5b/6)/(5b/6-b)]+[(b)/(5b/6-b)]
=>[(5b/6)÷(5b-6b)/6]÷[b/(5b-6b)/6]
=>[5b/-b]÷[6b/-b]
=>(5b/-b)*(-b/6b)
=>(5b/6b)=>[5/6] ans.
