Question

if you subtract 1/2 from a number and multiply the result by 1/2, you get 1/8. what is the number ?

Answer 1

Let the number be x.

Therefore , when we subtract 1/2 from it and multiply by 1/2 , we get 1/8.

(x-1/2 ) × 1/2 = 1/8

or, (2x-1)/2 × 1/2 = 1/8

or, (2x-1)/4 = 1/8

or, 2x-1 = 1/8 × 4

or, 2x = 1/2 + 1

or, 2x = 3/2

or, x = 3/2/2

or, x = 3/4

Answer → Our Number is 3/4.
