julyap $\frac{7}{18} : \frac{14}{54} = \frac{7*54}{18*14} = \frac{3}{2} =1.5 \\ \\ \frac{8}{15} : \frac{16}{45} = \frac{8*45}{15*16} = \frac{3}{2} =1.5 \\ \\ \frac{35}{78} : \frac{5}{14} = \frac{35*14}{78*5} = \frac{7*7}{39} = \frac{49}{39} =1 \frac{10}{39} \\ \\ \frac{11}{36} * \frac{33}{72} = \frac{11*72}{36*33} = \frac{2}{3} \\ \\ \frac{19}{81} : \frac{38}{90} = \frac{19*90}{81*38} = \frac{10}{9*2} = \frac{5}{9}$

$\frac{8}{90} : \frac{16}{30} = \frac{8*30}{90*16} = \frac{1}{3*2} = \frac{1}{6}$
