Let the number should be subtracted to be x.

According to the Question

It is given that when we subtract

$\bold{\bf{ x \: from \: \frac{ - 3}{8} \: gives \: \frac{13}{72} }}$

$\bf{we \: write \: this \: as \: a \: equation }$

$\implies \frac{-3}{8}-x=\frac{13}{72} \\ \implies-x=\frac{13}{72}+\frac{3}{8}\\ \implies-x=\frac{13+27}{72} \\ \implies-x=\frac{\cancel{40}^{ \: \: \: \: \: 5}}{\cancel{72_ { \: \: \: 9}}} \\ \implies \boxed {x=\frac{-5}{9}}$
