Question

if 1 is added to the numerator of a fraction it becomes 1 and if 4 is added to the denominator it becomes 1/2​

Answer 1

Answer:

Let the fraction be x/y

case1=x/y+1=1/2

           2x=y+1

           2x-y=1           .........................eq1

case 2=x+1/y=1

          =x+1=y

          =y-x=1           ..........................eq2

add eq1+2

2x-y+y-x=1+1

x=2

put x=2 in eq 2

y-2=1

y=3
