If you subtract 1/2 from a number and multiply the result by 1/2, you get 1/8. What is the number? About the author Vivian
Let the number be x . A\Q (x – 1/2) × 1/2 = 1/8 => 1/2x – 1/4 = 1/8 => 1/2x = 1/8+1/4 => 1/2x = 1/8 +1×2/4×2 => 1/2x = 1/8 + 2/8 => 1/2x = 1+2/8 => 1/2x = 3/8 => x = 3×2/8×1 => x = 6/ 8 By canceling x= 3/4 answer is 3/4 Reply
Let the number be x .
A\Q
(x – 1/2) × 1/2 = 1/8
=> 1/2x – 1/4 = 1/8
=> 1/2x = 1/8+1/4
=> 1/2x = 1/8 +1×2/4×2
=> 1/2x = 1/8 + 2/8
=> 1/2x = 1+2/8
=> 1/2x = 3/8
=> x = 3×2/8×1
=> x = 6/ 8
By canceling
x= 3/4
answer is 3/4
