Question

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

Answer 1

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. (By taking LCM )

x/2=3/8

x=3/4

Answer 2

(x-1/2)*1/2=1/8

x-1/2=1/8*2/1

x-1/2=1/4

X=1/4+1/2

X=1+2/4

X=3/4
