            The sum of the numerator and the denominator of a fraction is 12 . If the denominator is increased by 3 , the fraction becomes​

Answer 1

ANSWER

Let the required fraction be

y

x

. Then,

x+y=12 .......(1)

And,

y+3

x

=

2

1

2x−y=3 .......(2)

On adding 1 and 2, we get,

x=5

On putting x=5 in equation 1, we get,

y=7

Therefore, the required fraction is

7
