Question

If you subtract $\frac{1}{2}$ from a number multiply the result by $\frac{1}{2}$ you get $\frac{1}{4}$. What is the number ?

Answer 1

let the number be $x$

according to the question

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

solving, we get

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

$\therefore x=1$
