Answer 1

Answer:

let the denominator be x

then , numerator - x-2

A/Q

denominator = x+1

x+1 = 1/2

x = 1/2-1

x = -1/2

numerator = -1/2-2

= -5/2

then fraction

-5/2

_______

-1/2

= 5/1 answer

Answer 2

Answer:

Let the numerator be x

Denominator = x+2

When 1 is added to Denominator:-

Denominator = x+2+1=x+3

A.T.Q.

(x)/(x+3)=1/2

Cross multiplying

x+3=2x

2x-x=3

x=3

Original Numerator = x = 3

Original Denominator = x+2 = 3+2 = 5

Original fraction = 3/5

Verification:-

Fraction = 3/5

1 is added to the Denominator:-

3/(5+1) = 1/2

3/6 = 1/2

1/2 = 1/2

Hence verified
