8)

$10$

Explicación paso a paso:

$3 \frac{2}{5} \times 1 \frac{2}{6} = \frac{17}{5} \times \frac{8}{6} = \frac{136}{30} = \frac{68}{15} \\ 3 \frac{1}{4} \times 2 \frac{2}{9} = \frac{13}{4} \times \frac{20}{9} = \frac{260}{36} = \frac{65}{9} \\ 2 \frac{1}{2} \times 1 \frac{1}{4} \times 3 \frac{1}{5} = \frac{5}{2} \times \frac{5}{4} \times \frac{16}{5} = \frac{400}{40} = 10$
