Answer:
[tex]227 \frac{1}{16} [/tex]
Step-by-step explanation:
[tex]15 \frac{3}{4} \times (7 \frac{3}{4} + 6 \frac{2}{3} ) [/tex]
[tex] = \frac{63}{4} \times ( \frac{31}{4} + \frac{20}{3} )[/tex]
[tex] = \frac{63}{4} \times ( \frac{93}{12} + \frac{80}{12} )[/tex]
[tex] = \frac{63}{4} \times \frac{173}{12} [/tex]
[tex] = 227\frac{1}{16} [/tex]
