Question

if you subtract 1/2 from a number and multiply the result by 1/2 you get 1/8. what is the number?? (pls provide steps)

Answer 1

`Number\ is\ (3)/(4)`

Explanation:

Let the number be x

Subtract 1/2 from x = (x - 1/2)

Multiply 1/2 to the result = 1/2(x - 1/2)

The result is 1/8

That is,

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