Question

if you subtract 1/2from a number and multiply the result by 1/2 , you get 1/8 what is the number

Answer 1

hey !!! bro here is your answer
let the no. be x
(x-1/2)1/2=1/8
x/2-1/4=1/8
x/2=1/8+1/4
3/8=x/2
3/8×2=3/4=x

Answer 2

let the unknown number be x.
x-1/2=(2x-1)/2.
the result is (2x-1)/2.
according to the question,
(2x-1)/2*1/2=1/8
(2x-1)/4=1/8
on cross multiplication we get
16x-8=4
16x=12
x=3/4
the required number is 3/4
