​

Answer 1

Answer : y-2=1

Step-by-step explanation:

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
