u can see steps

$3 \: is \: a \: factor \: of \: 33 \: \\ \\ 25 \: and \: 55 \: and \: 20\: have \: commom \: factor \: 5 \\ \\ 9 \: is \: factor \: of \: 18 \:$

$\frac{33}{20} \times \frac{25}{9} \times \frac{18}{55} \times \frac{2}{3} \\ \\ \frac{11}{2} \times \frac{1}{1} \times \frac{2}{11} \times \frac{1}{1} \\ \\ \frac{11}{2} \times \frac{2}{11} \\ \\ 1$
