$\frac{3}{6} \times \frac{1}{2} = \frac{1}{4}$

➢

$\frac{5}{7} \times \frac{3}{8} = \frac{15}{32}$

➢

$\frac{4}{8} \times \frac{1}{4} = \frac{1}{8}$

➢

$2 \frac{1}{2} \times 3 \frac{2}{5} = 8 \frac{1}{2}$

➢

$\frac{8}{14} \times \frac{1}{2} = \frac{2}{7}$

➢

$\frac{3}{4} \div \frac{1}{4} = 3$

➢

$1 \frac{2}{3} \div 2 \frac{3}{5} = \frac{25}{39}$

➢

$\frac{3}{9} \div \frac{2}{3} = \frac{1}{2}$

➢

$1 \frac{3}{7} \div 2 \frac{1}{6} = \frac{60}{91}$

➢

$2 \frac{4}{5} \div \frac{3}{10} = 9 \frac{1}{3}$
