3/5 : 7/6 =

Answer 1

$\frac{1}{6} + \frac{2}{6} + \frac{3}{6} = \\ \\ \frac{1 + 2 + 3}{6} = \\ \\ 6 \frac{6}{6} = \\ \\ = 1 \\ \\ \frac{5}{6} - \frac{3}{8} = \\ \\ \frac{3 \times 4}{5 \times 4} - \frac{3 \times 8}{8 \times 3} = \\ \\ \frac{20}{24} - \frac{9}{24} = \\ \\ \frac{20 - 9}{24} = \\ \\ \frac{11}{24} \\ \\ \frac{3}{4} + \frac{3}{10} = \\ \\ \frac{3 \times 5}{4 \times 5} + \frac{3 \times 2}{10 \times 2} = \\ \\ \frac{15}{20} + \frac{6}{20} = \\ \\ \frac{15 + 6}{20} = \\ \\ \frac{21}{20} \\ \\ \frac{4}{6} \div \frac{7}{3} = \\ \\ \frac{4}{6} \times \frac{7}{3} = \\ \\ \frac{4}{2} \times \frac{1}{7} = \\ \\ 2 \times \frac{1}{7} = \\ \\ \frac{2}{1} \times \frac{1}{7} = \\ \\ \frac{2 \times 1}{1 \times 7} = \\ \\ \frac{2}{7} \\ \\ \frac{2}{7} \times \frac{3}{2} = \\ \\ \frac{1}{7} \times \frac{3}{2 } = \\ \\ \frac{1 \times 3}{7 \times 2} = \\ \\ \frac{3}{14} \\ \\ \frac{3}{5} \div \frac{7}{6} = \\ \\ \frac{3}{5} \times \frac{6}{7} = \\ \\ \frac{3 \times 6}{5 \times 7} = \\ \\ \frac{18}{35}$
