Question
What should be subtracted from $-2$ to get $\frac{3}{8}$ ?
✓
Answer
Set the required number be $=x$
According to the condition,
$-2-x=\frac{3}{8}$
$ \Rightarrow-x=\frac{3}{8}+2$
$ \Rightarrow-x=\frac{3+16}{8}$
$ \Rightarrow x =\frac{-19}{8}$
$\therefore$ The required number $=\frac{-19}{8}$
