Question

the numerator(N) of a fraction is 4 less than the denominator(D) . If one is added to both N and D , it becomes 1/2 . Find the fraction? ​

Answer 1

Answer:

Step-by-step explanation:

Let the denominator be x

Then, the numerator be 4 - x

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

1 / 4 + 1 = 1/2

Therefore, the fraction is 5 / 4 ...

Answer 2

Step-by-step explanation:

Given that

The numerator of a fraction is 4 less than the denominator

1 is added to both its numerator and denominator, it becomes 1/2.

So let the fraction to be predicted a/b

As per the given condition

Numerator= denominator-4

a=b−4

=b−a=4

As per the given data

if 1 added to both numerator and denominator then fraction becomes 1/2

a+1 / b+1 = 1/2

On cross multiplying the above equation we get,

2a+2=b+1

2a−b=−1

(2a−b)+(b−a)

=4−1

a=3,

and b=7

Fraction= 3/7
