Answer 1

Let, the unknown number = x
Given series of steps and solution:
                 (x - 1/2) * 1/2 = 1/8
                  x - 1/2 = 1/8 / 1/2
                   x - 1/2 = 1/4
                   x = 1/4 + 1/2
                    x = 1+2 / 4
                     x = 3/4
∴ The required number is 3/4
