Question

the numerator of a fraction is 2 more than its numerator if 3 is added in numerator and 9 is added in you later then fraction becomes 1 by 2 find the fraction

Answer 1

Let denominator be x
numerator =2+x
2+x+3/x+9=1/2
5+x/x+9=1/2
x+9=2(5+x)
x+9=10+2x
-2x+x=10-9
-x=1 or x=-1
Numerator =2+(-1)=1
fraction = 1/-1 i.e. -1
