Question

If you subtract 1/2 from a number and multiply the result with 1/2 you get 1/8 what is the number?

Answer 1

Hey friend,

Here's your answer:
Let that number be x.

=> (x - 1/2)1/2 = 1/8.
=> ((2x - 1)2)/2 = 1/8 (LCM)
=> 2x - 1 = 1/8
=> 2x = 1/8 + 1
=> 2x = (1 + 8)/8
=> 2x = 9/8
Therefore x = 9/16.

Therefore the number is (3/4)² = 9/16

Hope my answer helps you.

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
