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

let the no. be x
so (x-1/2)1/2=1/8
x-1/2=1/4
x=3/4

Answer 2

Answer:

The number is 3/4.

Step-by-step explanation:

Let the number be x.

According to question,

     (1/2) * (x – 1/2) = 1/8

=> (x – 1/2) = (1/8) * (2/1)

=> x – 1/2 = 2/8

=> x -1/2 = 1/4

=> x = 1/4 + 1/2

=> x = (1 + 2)/4

=> x = 3/4

Hence, the number is 3/4
