$\frac{15}{11} * \frac{2}{3} * \frac{22}{5}$

$\frac{35}{33} : \frac{5}{11} : \frac{7}{3}$

Answer 1

$\displaystyle{ \frac{15}{11}} * { \frac{2}{3} * { \frac{22}{5} }= \frac{30}{33} * \frac{22}{5} = \frac{660}{165} =4$

$\displaystyle \frac{35}{33} : \frac{5}{11} : \frac{7}{3} = \frac{35}{33} * \frac{11}{5} * \frac{3}{7} = \frac{385}{165} * \frac{3}{7} = \frac{1155}{1155} =1$
