4)

$a)7 \times \frac{3}{5} = \frac{21}{5}$

$b)2 \times \frac{5}{8} = \frac{10}{8} = \frac{5}{4}$

$c) \frac{1}{3} \times 12 = \frac{12}{3} = 4$

$d) \frac{7}{56} \times 14 = \frac{7}{4}$

$e) \frac{3}{5} \times 1 = \frac{3}{5}$

$f) \frac{2}{5} \times \frac{3}{7} = \frac{6}{35}$

$g) \frac{1}{9} \times \frac{3}{5} = \frac{3}{45} = \frac{1}{15}$

$h) \frac{4}{5} \times \frac{11}{8} = \frac{44}{40} = \frac{11}{10}$

$i) \frac{17}{10} \times \frac{20}{3} = \frac{17 \times 2}{3} = \frac{34}{3}$

$j)1 \frac{1}{3} \times \frac{3}{4} = \frac{4}{3} \times \frac{3}{4} = 1$

$k)3 \frac{4}{7} \times \frac{2}{15} = \frac{25}{7} \times \frac{2}{15} = \frac{5 \times 2}{7 \times 3} = \frac{10}{21}$

$l) \frac{9}{8} \times 1 \frac{3}{5} = \frac{9}{8} \times \frac{8}{5} = \frac{9}{5}$
