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

Step-by-step explanation:

Let us consider the number be x

As per the given condition

If we subtract 1/2 from a number and multiply the result by 1/2, then we get 1/8.

So the equation becomes

⇒ (1/2)(x – 1/2) = (1/8)

⇒  (x – 1/2) = (1/4)

⇒ 4x – 2 = 1

⇒  4x = 3

Hence x = 3/4

Therefore 3/4 is the number from which if we subtract 1/2 from a number and multiply the result by 1/2, we get 1/8.

Answer 2

Answer: the number is 3/4

Step-by-step explanation:

Let the number be x

$(x-1/2)1/2=1/8\\x/2-1/4=1/8\\x/2=1/8+1/4\\x/2=1/8+2/8\\x/2=3/8\\x=2*3/8\\x=6/8\\x=3/4$
