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 

so according to question (x - 1/2 )1/2 = 1/8 

⇒ x - 1/2 = 1/4 

⇒ x = 3/4 ANSWER

Answer 2

Answer:

Required number (x) =$\frac{3}{4}$

Step-by-step explanation:

Let the number be x

i ) Subtracting $\frac{1}{2}$ from the number = $x-\frac{1}{2}$ ----(1)

Now,

According to the problem given,

"subtract 1/2 from a number and multiply the result by 1/2, you get 1/8"

$(x-\frac{1}{2})\times \frac{1}{2} = \frac{1}{8}$

$\implies (x-\frac{1}{2}) = \frac{1}{8} \times \frac{2}{1}$

$\implies x - \frac{1}{2} = \frac{1}{4}$

$\implies x = \frac{1}{4}+\frac{1}{2}$

$\implies x = \frac{(1+2)}{4}$

$\implies x = \frac{3}{4}$

Therefore,

Required number (x) =$<strong> </strong>\frac{3}{4}$
