let number be x
add 1/3 then it is x+1/3
multiply by 2
(x+1/3)×2 =8/3
2x +2/3 =8/3
2x=8/3 -2/3
2x=6/3
2x=2
x=2/2
x=1 is number
add 1/3 then it is x+1/3
multiply by 2
(x+1/3)×2 =8/3
2x +2/3 =8/3
2x=8/3 -2/3
2x=6/3
2x=2
x=2/2
x=1 is number

Just reverse the process. It means:
(8/3)/2=4/3
4/3-1/3=3/3=1
(8/3)/2=4/3
4/3-1/3=3/3=1
