$a)3 \frac{3}{5} \times 2 \frac{1}{12} \\ \frac{18}{5} \times \frac{25}{12} = \frac{15}{2 } = 7 \frac{1}{2}$

$b)1 \frac{7}{8} \times 2 \frac{2}{5 } \\ \frac{15}{8} \times \frac{12}{5} = \frac{9}{2} = 4 \frac{1}{2}$

$v)2 \frac{2}{21} \times 3 \frac{1}{2} \\ \frac{44}{21} \times \frac{7}{2} = \frac{22}{3} = 7 \frac{1}{3}$

$g)6 \frac{1}{9} \times 1 \frac{2}{7 } \\ \frac{55}{9} \times \frac{9}{7} = \frac{55}{7} = 7 \frac{6}{7}$
