Question

The numerator of fraction is 1 less than its denominator . If the numerator is increased by 4 and the denominator is increased by 5 the new fraction becomes equivalent to 4/5 .What is the original fraction ?​

Answer 1

Answer:

Let the denominator be x.

So ,the numerator becomes x-1.

Original fraction =x-1/x

According to the question  

x-1+4/x+5=4/5

x+3/x+5=4/5

5 (x+3)=4 (x+5)

5x+15=4x+20

5x-4x=20-15

x=5

Original fraction =x-1/x

= 5-1/5

= 4/5
