Question

In a fraction when 3 is added to its numerator and denominator it becomes 4/5. And it becomes 1/2 when 2 is subtracted from both the numerator and denominator. Find the fraction.

Answer 1

Answer:

Step-by-step explanation:

Let the fraction be x/y. Then by the given question,

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

or, (x+2)/y-x/y=-1/2

or,( x+2-x)/y=-1/2

or, 2/y=-1/2

or, y/2=-2

or, y=-4

x/(y-1)=x/y-1/3

or, x/(-4-1)=x/(-4)-1/3

or, -x/5=-x/4-1/3

or, -x/5+x/4=-1/3

or, (-4x+5x)/20=-1/3

or, x/20=-1/3

or, x=-20/3

then, x/y=(-20/3)/-4=5/3
