The denominator of a fraction is exceed by 2 and 5 is added to

Answer»

I am considering that your question is like this:-

The denominator of a fraction exceeds the numerator by 2. If 5 be added to the numerator the fraction increase by UNITY. The fraction is? 
Here is the answer :-

Numerator = x


then,

Denominator = x + 2

(x+5)/(x+2) = x/ (x+2) +1

(x+5)/(x+2) - x/(x+2) =1

(x+5 -x)/(x+2)= 1

5/(x+2) = 1

5 = x + 2

x = 3

so,

numerator = x = 3
denominator = x+2 = 3+2 = 5

Fraction = 3/5

:D
