Question

What should be subtracted from $\frac{-3}{4}$ to get 1?

Answer 1

$\begin{array}{l}\text{Let the required}\text{number that is to be subtracted}\mathrm{be}\mathit{\text{x}}.\\ \\ \frac{-3}{4}-x=1\\ =>-x=1-\frac{(-3)}{4}\\ \\ =>-x=\frac{4+3}{4}\\ =>-x=\frac{7}{4}\\ \\ =>x=-\frac{7}{4}\\ \end{array}$
