Question

if the numerator of a fraction is increased by 25%and the denominator is increased by 10%,it becomes 2/5.find the original fraction ​

Answer 1

Answer:

5/11

Step-by-step explanation:

let the numerator be x and denominator be y

It is given that the numerator of the fraction is increased by 25% and denominator of the fraction is increased by 10%

putting the value in numerator x+x/4

putting the value in denominator y+y/10

we get x+x/4/y+y/10 = 2/5

4x+4/4/10y+y/10 = 2/5

5x/4/11y/10 = 2/5

25x/22y = 2/5

from this equation we get x/y = 2*25/5*22= 5/11

Hence the value of x/y is 5/11.
