Answer:
Let us consider the number be x
As per the given condition
If we subtract 1/2 from a number and multiply the result by 1/2, then we get 1/8.
So the equation becomes
⇒ (1/2)(x – 1/2) = (1/8)
⇒ (x – 1/2) = (1/4)
⇒ 4x – 2 = 1
⇒ 4x = 3
Hence x = 3/4
Therefore 3/4 is the number from which if we subtract 1/2 from a number and multiply the result by 1/2, we get 1/8.

Step-by-step explanation:
Let the required number be k
First subtracting ½ from k , so the result found is k - ½
A/Q → ( k - ½ ) × ½ = 1/8
→ k - ½ = 2/8
→ ( 2k - 1 ) / 2 = 1/4
→ 2k - 1 = ½
→ 2k = ½ + 1
→ 2k = 3/2
k = 3/4 ANS.
So the required number is 3/4 .
