Answer 1

Resposta:

$a)\frac{2}{3}*\frac{27}{8}=\frac{54}{24}=\frac{9}{4}\\\\b)\frac{5}{8}*\frac{2}{25}=\frac{10}{200}=\frac{1}{20}\\\\c)\frac{16}{5}*\frac{5}{4}=\frac{80}{20}=4\\\\d)\frac{2}{3}*\frac{9}{5}*\frac{25}{4}=\frac{450}{60}=\frac{15}{2}\\\\e)\frac{12}{5}*\frac{5}{6}*\frac{1}{7}=\frac{2}{7}$

$f)\frac{7}{36}*\frac{1}{7}*\frac{6}{5}=\frac{42}{1260}=\frac{1}{30}\\\\g)6*\frac{3}{4}=\frac{18}{4}=\frac{9}{2}\\\\h)10*\frac{3}{5}=\frac{30}{5}=6$

$i)\frac{6}{5}*\frac{2}{3}=\frac{12}{15}=\frac{4}{5}\\\\j)\frac{1}{3}*\frac{2}{5}=\frac{2}{15}$
