If you subtract ½ from a number and multiply the result by ½, you got 1/8. What is the number?

Let the number be x.
According to the question, 1/2(x-1/2)=1/8
⇒ 2×1/2(x-1/2)=1/8×2 [Multiplying both sides by 2]
⇒ x-1/2=1/4
⇒ x-1/2+1/2=1/4+1/2 [Adding both sides1/2]
⇒ x=1+2/4 ⇒ x=3/4
Hence, the required number is 3/4
