Answer

$$3\frac{5}{8} $$

Work Step by Step

In order to add or subtract fractions, we start by making a common denominator (bottom of the fraction). Then, we subtract the numerators from each other. Doing this, we find: $$ 8 -4\frac{3}{8} \\ \frac{64}{8} - \frac{35}{8} \\ \frac{29}{8} \\ 3\frac{5}{8} $$
