Answer 1

$2 \times \frac{2}{3} = \frac{4}{3}$

$3 \times \frac{2}{5} = \frac{6}{5}$

$\frac{1}{8} \times 5 = \frac{5}{8}$

$\frac{6}{3} \times 1 = \frac{6}{3}$

$2 \times \frac{2}{3} \times \frac{1}{7} = \\ \frac{4}{21}$

$\frac{2}{5} \times 3 \times \frac{4}{8} = \frac{24}{40} = \frac{12}{20} = \frac{6}{10} = \frac{3}{5}$

$5 \times \frac{2}{3} \times 7 = \frac{70}{ 3}$

$\frac{7}{5} \times 2 \times 4 = \frac{56}{5}$
