Răspuns:

$a)2 \times \frac{3}{5} = \frac{2 \times 3}{5} = \frac{6}{5} \\ b)3 \times \frac{2}{5} = \frac{3 \times 2}{5} = \frac{6}{5} \\ c)7 \times \frac{2}{5} = \frac{7 \times 2}{5} = \frac{14}{5} \\ d)2 \times \frac{7}{5} = \frac{2 \times 7}{5} = \frac{14}{5} \\ e)6 \times \frac{3}{4} = \frac{6 \times 3}{4} = \frac{18}{4} = \frac{9}{2} \\ f)3 \times \frac{3}{2} = \frac{3 \times 3}{2} = \frac{9}{2} \\ g)20 \times \frac{7}{25} = \frac{20 \times 7}{25} = \frac{140}{25} = \frac{28}{5} \\ h) \frac{1}{36} \times 21 = \frac{1 \times 21}{36} = \frac{21}{36} = \frac{7}{12}$
