Question

The number of a fraction
is 4 less than the
denominatos. if 1 is added to
both its numerator and denominator
it becomes half . Find the fraction​

Answer 1

Step-by-step explanation:

Numerator= 4 less than denominator = x-4

Denominator = x

When 1 is added becomes 1/2

x-4+1/x+1 = 1/2

x-3/x+1 = 1/2

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

2x-6=x+1

2x-x = 1+6

x = 7
