Question

If you subtract 1/2 from a no. and multiply the result by 1/2,
you get 1/8. What is the number?
​

Answer 1

Step-by-step explanation:

ALGEBRA MEATHOD

let the no. be x

then, According to the question (ATQ)

It is given that ...

(x-1/2)× 1/2 = 1/8

now, we have made the equation..

by solving..

x/2 - 1/4 = 1/8

on taking LCM..

LCM = 4

2x/4 - 1/4 = 1/8

2x - 1/4

by cross multiplication..

8(2x-4) = 1×4

16x - 4 = 4

16x = 4+4

16x = 8

x = 8/16

x = 1/2
