Answer
$36 \cdot \frac{5}{8} \cdot \frac{9}{15} =\frac{27}{2}$
Work Step by Step
$36 \cdot \frac{5}{8} \cdot \frac{9}{15} = \frac{36}{1} \cdot \frac{5}{8} \cdot \frac{9}{15} = \frac{36}{1} \cdot \frac{1}{8} \cdot \frac{9}{3} = \frac{36}{1} \cdot \frac{1}{8} \cdot \frac{3}{1} = \frac{9}{1} \cdot \frac{1}{2} \cdot \frac{3}{1} = \frac{9 \cdot 1 \cdot 3}{1 \cdot 2 \cdot 1} =\frac{27}{2}$
