Resposta:

 \frac{1}{6}  \div  \frac{3}{5}  =  \frac{1}{6}  \times   \frac{5}{3}  =  \frac{5}{18}

  \frac{3}{4}   \div  \frac{2}{9}  =  \frac{3}{4}  \times  \frac{9}{2}  =  \frac{27}{8}

3 \div  \frac{1}{45}  =  \frac{3}{1}  \times  \frac{45}{1}  =  \frac{135}{1}  = 135

20 \div  \frac{4}{5}  = 20 \times  \frac{5}{4}  =  \frac{100}{4}  = 25

2 \frac{1}{ 3}  \div 4 \frac{2}{6}  =  \frac{7}{3}  \div  \frac{14}{6}  \\  =  \frac{7}{3}  \times  \frac{6}{14}  =  \frac{42}{42}
