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

Answer:

$\frac{3}{4}$

Step-by-step explanation:

Let the unknown number be $x$

According to the condition given in the question,

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

$\frac{x}{2}-\frac{1}{4}=\frac{1}{8}$

$\frac{2x}{4}-\frac{1}{4}=\frac{1}{8}$

$\frac{2x-1}{4}=\frac{1}{8}$

$2x-1=\frac{4}{8}$

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

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

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

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

$2x=\frac{3}{2}$

$x=\frac{3}{2\times2}$

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

∴ The number is $\frac{3}{4}$.
