$4 \times \frac{3}{8} = \frac{4 \times 3}{8} = \frac{12}{8} = \frac{3}{2}$

d)

$6 \times \frac{5}{9} = \frac{6 \times 5}{9} = \frac{30}{9} = \frac{10}{3}$

2) a)

$\frac{3}{2} \times \frac{3}{5} = \frac{3 \times 3}{2 \times 5} = \frac{9}{10}$

c)

$\frac{4}{5} \times \frac{7}{3} = \frac{4 \times 7}{5 \times 3} = \frac{28}{15}$

d)

$\frac{8}{3} \times \frac{5}{7} = \frac{8 \times 5}{3 \times 7} = \frac{40}{21}$
