Let the number be 'x'

$(x - 1/2) * 1/2 = 1/8$

$(2x-1/2) * 1/2 = 1/8$

$(2x - 1/2) = 1/4$

$2x - 1 = 1/2$

$2x = 1/2 + 1$

$2x = 3/2$

$x = 3/4$

Answer 2

Hi....✌✌

Let the no. be x

Then

(x - 1/2 ) 1/2 = 1/8

{(2x -1)÷2 } 1/2 = 1/8

(2x-1) ÷ 4 = 1/8
2x-1 = 4/8
2x-1 = 1/2
2x = 1/2 + 1
2x = 3/2
x = 3/4
