CORRECT QUESTION:

If you subtract ½ from a number and multiply the result by ½ you get ⅛. What is the number？

CORRECT SOLUTION:

Let the required number be x.

According to the Question ,

If we substract ½ from x and multiply the result by ½ we get ⅛ .

→ (x - ½) × (½) = ⅛

→ x - ½ = ⅛ × ²/₁

→ x - ½ = ²/₈

→ x - ½ = ¼

→ x = ½ + ¼

→ x = (2+1)/4

→ x = ¾

∴ The required number is ¾.
