Answer 1

Explicação passo-a-passo:

$50 \div \frac{2}{7} = \frac{50}{1} \times \frac{7}{2} = \frac{350}{2} = 175 \\ \\ 120 \div \frac{4}{3} = \frac{120 }{1} \times \frac{3}{4} = \frac{360}{4} = 90 \\ \\ 75 \div \frac{3}{10} = \frac{75}{1} \times \frac{10}{3} = \frac{750}{3} = 250 \\ \\ 65 \div \frac{47}{103} = \frac{65}{1} \times \frac{103}{47} = \frac{6695}{47} = 142.4$
