Question

if you substract 1/3 from a number and multiply the result by 1/3,you get 1/8.what is the number

Answer 1

This is simple
1/8 = 0.125
1/2 =0.5
so as per as the question 0.125/0.5 =0.25
then 0.25 + 0.5 = 0.75
so the answer is 0.75 or 3/4


Answer 2

let a number = Y
(Y-1/3) x 1/3 = 1/8
Y-1/3 = 1/8 divided by 1/3
Y-1/3 = 1/8 x 3/1
Y-1/3 = 3/8
Y      = 3/8 + 1/3
Y      = 9/24 + 8/24
   Y   = 17/24
