Answer 1

Explicação passo-a-passo:

$h) \frac{9}{5} \times1 \frac{2}{3} + \frac{7}{10} \\ \frac{9}{5} - \frac{5}{3} + \frac{7}{10} = \frac{5}{6} \\ i) \frac{2}{3} \times \frac{2}{5} = \frac{4}{15} \\ j)2 \times 5 \times \frac{9}{2} \\ 5 \times 9 = 45 \\ k) \frac{14}{3} \div \frac{7}{3} \\ \frac{14}{3} \div \frac{3}{7} = 2 \\ l)2 \times \frac{5}{4} = \frac{5}{2} \\ m) \frac{6}{15} \times \frac{3}{2} = \frac{3}{5} \\ n) \frac{9}{4} \div \frac{25}{7} \\ \frac{9}{4} \times \frac{7}{25} = \frac{63}{100} \\ o) \frac{ \frac{2}{3} }{20} = \frac{1}{30}$
