Answer»

Answer:

LET FRACTION is x/y

add 1numerater and denominator

x+1/y+1=4/5

5x+5=4y+4

5x_4y= -1 –equ. 1

now 5 is subtract numerator and denominator

x-5/y-5=1/2

2x-10=y-5

2x-y=5_equ.2

comparing EQUESTION 1ST and 2nd

5x-4y=-1

8x-4y=20

add both

-3x=-21

x=7

put this value in equ. 1

5(7)-4y=-1

35-4y=-1

-4y=-1-35

-4y=-36

y=9

therefore fraction is 7/9
