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

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

Answer 2

Answer:

3/4

Step-by-step explanation:

Let the number be x.

According to the question,

→ (x – 1/2) × ½ = 1/8

=> x/2 – ¼ = 1/8

=> x/2 = 1/8 + ¼

=> x/2 = 1/8 + 2/8

=> x/2 = (1+ 2)/8

=> x/2 = 3/8

=> x = (3/8) × 2

=> x = ¾
