Step-by-step explanation:
[tex]24 \frac{1}{2} + 15 \frac{3}{8} \\ \\ = \frac{24 \times 2 + 1}{2} + \frac{15 \times 8 + 3}{8} \\ \\ = \frac{48+ 1}{2} + \frac{120 + 3}{8} \\ \\ = \frac{49}{2} + \frac{123}{8} \\ \\ = \frac{49 \times 4}{2 \times 4} + \frac{123}{8} \\ \\ = \frac{196}{8} + \frac{123}{8} \\ \\ = \frac{196 + 123}{8} \\ \\ = \frac{319}{8} \\ \\ = 39 \frac{7}{8} [/tex]
