0 If we add 1 to the numerator and subtract 1 from the denominator, a fraction reduce
to 1. It becomes 1/2
if we only add 1 to the denominator. What is the fraction?

heyy mate!!!
let the fraction be x/ y
now, according to the first condition,
x+1/ y-1=1
by cross multiplication,
( x+1)=y-1
x-y= -1-1
x-y= -2.... (1)
now,
x/ y+1= 1/2
by cross multiplication,
2x= y+1
2x- y= 1....(2).
now multiplying equation (1) by 2,
2(x-y) = -2× 2
2x- 2y= -4.... (3)
by subtracting eq (3) from (2)
2x-y = 1
-2x + 2y= 4
y= 5
substititing value of y in eq (1)
we get,
x-y =-2
x-5= -2
x= 5-2
x= 3
therefore,
the required fraction is
x/y= 3/5
Answer:
the fraction is 3/5
let the numerator be x and denominator be y
find the eq I
then, find eq ii
solve it
,x=3
y=5
