ex. 3

$a) \frac{2}{11}: \frac{3}{5}= \frac{2}{11}* \frac{5}{3}= \frac{10}{33}$

$b) \frac{1}{4}: \frac{7}{5}= \frac{1}{4}* \frac{5}{7}= \frac{5}{28}$

$c) \frac{5}{6}: \frac{7}{3}= \frac{5}{6}* \frac{3}{7}= \frac{5}{2}* \frac{1}{7}= \frac{5}{14}$

$d) \frac{1}{3}: \frac{2}{9}= \frac{1}{3}* \frac{9}{2}= 1* \frac{3}{2}= \frac{3}{2}$

$e) \frac{5}{9}: \frac{1}{6}= \frac{5}{9}* \frac{6}{1}= \frac{5}{3}* \frac{2}{1}= \frac{10}{3}$

$f) \frac{2}{7}: 1\frac{1}{3}= \frac{2}{7}: \frac{4}{3}= \frac{2}{7}* \frac{3}{4}= \frac{1}{7}* \frac{3}{2}= \frac{3}{14}$

$g) 5\frac{1}{2}: \frac{4}{3}= \frac{11}{2}: \frac{4}{3}= \frac{11}{2}* \frac{3}{4}= \frac{33}{8}$

$h) 5\frac{1}{2}: 10\frac{1}{4}= \frac{11}{2}: \frac{41}{4}= \frac{11}{2}* \frac{4}{41}= \frac{11}{1}* \frac{2}{41}= \frac{22}{41}$
