Question

The numerator of afraction is 4 less that the denomentor, if one is added to both, its numerator and denomenator becomea es 1/2. find the fraction​

Answer 1

Step-by-step explanation:

Let the denominator be X.

and the numerator be x-4 .

One is added to both.

Numerator = x-4+1

=x-3

Denominator = X+1

Numerator and denominator becomes 1/2.

x-3/X+1 =1/2

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

X + 1=2x -6

1+6=2x-x

7 = x

or X= 7

Numerator= x-3

= 7-3

= 4

Denominator= x+1

= 7+1

= 8

Required fraction=4/8

= 1/2
