Răspuns:

$a)\:3\frac{9}{14}:2\frac{3}{7}\times\frac{2}{3}=\frac{51}{14}:\frac{17}{7}\times\frac{2}{3}=\frac{\not51}{\not14}\times\frac{\not7}{\not17}\times\frac{2}{3}=\frac{\not3}{\not2}\times\frac{\not2}{\not3}=1$

$b)\:1\frac{7}{8}\times\frac{4}{9}:8\frac{1}{3}=\frac{15}{\not8}\times\frac{\not4}{9}:\frac{25}{3}=\frac{\not15}{2}\times\frac{1}{\not9}\times\frac{\not3}{\not25}=\frac{\not3}{2}\times\frac{1}{\not3}\times\frac{1}{5}=\frac{1}{2\times5}=\frac{1}{10}$

$c)\:3\frac{3}{8}:1\frac{1}{4}:\frac{3}{5}=\frac{\not27}{8}:\frac{5}{4}\times\frac{5}{\not3}=\frac{9}{\not8}\times\frac{\not4}{\not5}\times\not5=\frac{9}{2}$
