Question

the numerator of a fraction is 4 less than the denominator. If I is added to both the
nu
merator and denominator, the fraction becomes 1/2. Find the fraction​

Answer 1

Answer:

3/7 is the fraction

Step-by-step explanation:

Numerator is 4 less than the denominator so,

Numerator = X - 4

Denominator = X

If 1 is added then the fraction becomes

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

= X - 3 / X + 1 = 1/2

By cross multiplication we get,

= 2(x - 3) = x + 1

= 2x - 6 = X + 1

= 2x - X = 1 + 6

= X = 7

Numerator of the fraction = 7 - 4 = 3

Denominator = X = 7

Hence the fraction is 3/7
