Answer:7/9

Explantion:

Let the fraction be x/y

According to the question  

x+1/y+1=4/5

5x+5=4y+4

5x-4y=-1  -(1)

5 is subtracted means

x-5/y-5=1/2

2x-y=5-(2)

Multiply equation 1 and 2 by 2 and 5 respectively

Therefore-  

2(5x-4y=-1)=10x-8y=-2

5(2x-y=5)=10x-5y=25

10x-5y=25

10x-8y=-2

x=7,y=9

then the fraction  is 7/9

Hope it will help u
