Question

Tick (✓) the correct answer
What should be subtracted from $\frac{-3}{5}$ to get −2?
(a) $\frac{-7}{5}$
(b) $\frac{-13}{5}$
(c) $\frac{13}{5}$
(d) $\frac{7}{5}$

Answer 1

(d) $\frac{7}{5}$
Let the required number be x.

Now,

$$\begin{gathered} -\frac{3}{5}-x=-2 \\ \Rightarrow -\frac{3}{5}=-2+x \\ \Rightarrow x=\left(-\frac{3}{5}+2\right) \\ \Rightarrow x=\frac{\left(-3+10\right)}{5} \\ \Rightarrow x=\frac{7}{5} \end{gathered}$$
Thus, the required number is $\frac{7}{5}$
