Question

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

Answer 1

solution,

let the number be x,

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

so we need to solve this,

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

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

2x-1/2=1/4

so, 2x=1/4+1/2=6/8=3/4

hence, 2x=3/4,

so, x=3/8
