This question is similar as your question bit change the value you will get your answer.
Let the fraction be x/y
1 is added means
x+1/y+1=4/5
5x+5=4y+4
5x-4y=-1
5 is subtracted means
x-5/y-5=1/2
2x-y=5
2 eqn multilply by 5 and 1 eqn by 2
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
