Решение и ответ:

1 способ

$\displaystyle\[4\frac{{13}}{{16}}-2\frac{3}{8}=\frac{{77}}{{16}}-\frac{{19}}{8}=\frac{{77}}{{16}}-\frac{{2\cdot 19}}{{2\cdot 8}}=\frac{{77}}{{16}}-\frac{{38}}{{16}}=\frac{{77-38}}{{16}}=\frac{{39}}{{16}}=\boxed{2\frac{7}{{16}}}\]$

2 способ

$\displaystyle \[4\frac{{13}}{{16}}-2\frac{3}{8}=4\frac{{13}}{{16}}-2\frac{6}{{16}}=(4-2)+\left({\frac{{13}}{{16}}-\frac{6}{{16}}}\right)=2+\frac{7}{{16}}=\boxed{2\frac{7}{{16}}}\]$
