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
then , 

(X - 1/2)x 1/2= 1/8
⇒(2X - 1)/4  =  1/8
⇒2X - 1 = 4/8 = 1/2 
⇒2X = 1+1/2= 3/2
⇒X = 3/2  x  1/2  =  3/4 

hence the number is 3/4

Reply if its right 

Answer 2

$\huge\tt{Answer}$

The value of x = 3/4

Step-by-step explanation:

$\sf = (x - \frac{1}{2} \times \frac{1}{2} = \frac{1}{8} ) \\ \sf= \frac{1}{2} \times (x) - ( \frac{1}{2} ) \times ( \frac{1}{2} ) = \frac{1}{8} \\ \sf= \frac{x}{2} - \frac{1}{4} = \frac{1}{8} \\ \sf = \frac{x}{2} \frac{1}{8} + \frac{1}{4} \\ \sf = \frac{x}{2} = \frac{1 + 2}{8} \\ \sf = \frac{x}{2} = \frac{3}{8} \\ \sf = x = \frac{3}{4} \times 2 \\ = x = \frac{3}{4}$
