Question

if you subtract 1/2 from a number and multiply the result by 1/2 ,you get 1/8. What is the number?
​

Answer 1

Answer:

3/4

Step-by-step explanation:

let the no. be x

than,

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

now,

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

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

by cross multiplication

8*(2x - 1) = 1* 4

16x - 8 = 4

16x = 12

x = 12/16

x 3/4

therefore, the no. is 3/4

hope it help u

thanks
