Respuesta:

 \frac{2}{3}  \times  \frac{3}{8}  =   \frac{2 \times 3}{3 \times 8}  =  \frac{6}{24}  =  \frac{1}{4}

 \frac{3}{4}  \times  \frac{24}{5}  =  \frac{3 \times 24}{4 \times 5}  =  \frac{72}{20}  =  \frac{36}{10}  =  \frac{18}{5}

20 \times  \frac{15}{10}  \times  \frac{5}{6}  =  \frac{20 \times 15}{1 \times 10}  \times  \frac{5}{6}  =  \frac{300}{10}  \times  \frac{5}{6}  =  \frac{300 \times 5}{10 \times 6}  =  \frac{1500}{60}  =  \frac{150}{6}  =  \frac{75}{3}  = 25

 \frac{10}{2}  \times  \frac{6}{7}  \times  \frac{1}{9}  =  \frac{10 \times 6}{2 \times 7}  \times \frac{1}{9}  =  \frac{60}{14}  \times  \frac{1}{9}  =  \frac{60 \times 1}{14 \times 9}  =  \frac{60}{126}  =  \frac{30}{63}  =  \frac{10}{21}

 \frac{1}{3}  \div  \frac{3}{5}  =  \frac{1 \times 5}{3 \times 3}  =  \frac{5}{9}

 \frac{3}{5}  \div  \frac{24}{10}  =  \frac{3 \times 10}{5 \times 24}  =  \frac{30}{120}  =  \frac{1}{4}

 \frac{2}{7}  \div  \frac{4}{5}  =  \frac{2 \times 5}{7 \times 4}  =  \frac{10}{28}  =  \frac{5}{14}
