Răspuns:

Explicație pas cu pas:

$\frac{6}{11}:\frac{9}{22} = \frac{6}{11} \cdot \frac{22}{9} = \frac{4}{3}\\\\\frac{13}{14}:\frac{4}{39} = \frac{13}{14} \cdot \frac{39}{4} = \frac{507}{56}\\\\\frac{2}{3}:\frac{1}{6} = \frac{2}{3} \cdot \frac{6}{1} = 4\\\\\\\frac{3}{4}:\frac{21}{49} = \frac{3}{4} \cdot \frac{49}{21} = \frac{49}{28}$
