Question

What should be subtracted from $\frac{-4}{5}$ to get 1 ?

✓

Answer

Let the required rational number be $x$
Other number $=\frac{-3}{5}$
Difference of two number $=1$
According to question,
$ \begin{aligned} & \therefore \frac{-4}{5}-\mathrm{x}=1 \\ & \Rightarrow \frac{-4}{5}-1=\mathrm{x} \\ & \Rightarrow \mathrm{x}=\frac{-4-1 \times 5}{5}=\frac{-9}{5} \end{aligned} $
