Answer 1

$\frac{11}{4} \times \frac{8}{22} \times 5 =$

$= \frac{11}{4} \times \frac{2 \times 4}{2 \times 11} \times 5 = 5$

$\frac{24}{5} \times \frac{15}{7} \times 3 =$

$= \frac{3 \times 8}{5} \times \frac{3 \times 5}{7} \times 3 = \frac{216}{7} = 30 \frac{6}{7}$

$\frac{15}{4} \times \frac{44}{3} \times 11 =$

$= \frac{3 \times 5}{4} \times \frac{4 \times 11}{3} \times 11 = \frac{605}{3} = 201 \frac{2}{3}$
