Answer 1

Explicación paso a paso:

$3 \frac{2}{5} \div 2 \frac{1}{4} = \\ \\ ( \frac{5 \times 3 + 2}{5} ) \div ( \frac{4 \times 2 + 1}{4} ) = \\ \\ \frac{17}{5} \div \frac{9}{4} = \frac{68}{45}$

$4 \frac{1}{2} \div \frac{3}{5} = \\ \\ ( \frac{2 \times 4 + 1}{2} ) \div \frac{3}{5} = \\ \\ \frac{9}{2} \div \frac{3}{5} = \frac{45}{6} = \frac{15}{2}$

$3 \frac{1}{5} \times \frac{2}{3} = \\ \\ ( \frac{5 \times 3 + 1}{5} ) \times \frac{2}{3} = \\ \\ \frac{16}{5} \times \frac{2}{3} = \frac{32}{15}$

$2 \frac{2}{3} \times \frac{4}{7} = \\ \\ ( \frac{3 \times 2 + 2}{3} ) \times \frac{4}{7} = \\ \\ \frac{8}{3} \times \frac{4}{7} = \frac{32}{21}$

$6 \frac{3}{7} \div 3 \frac{1}{4} = \\ \\ ( \frac{7 \times 6 + 3}{7} ) \div ( \frac{4 \times 3 + 1}{4} ) = \\ \\ \frac{45}{7} \div \frac{13}{4} = \frac{180}{91}$

$5 \frac{1}{4} \times 2 \frac{3}{7} = \\ \\ ( \frac{4 \times 5 + 1}{4}) \times ( \frac{7 \times 2 + 3}{7} ) = \\ \\ \frac{21}{4} \times \frac{17}{7} = \frac{357}{28} = \frac{51}{4}$

$6 \frac{1}{8} \div 2 \frac{1}{4} = \\ \\ ( \frac{8 \times 6 + 1}{8} ) \div ( \frac{4 \times 2 + 1}{4} ) = \\ \\ \frac{49}{8} \div \frac{9}{4} = \frac{196}{72} = \frac{49}{18}$

$2 \frac{1}{5} \times 3 \frac{1}{4} = \\ \\ ( \frac{5 \times 2 + 1}{5} ) \times ( \frac{4 \times 3 + 1}{4} ) = \\ \\ \frac{11}{5} \times \frac{13}{4} = \frac{143}{20}$
