Answer 1

$3 \times \frac{7}{2} = \frac{21}{2}$

$5 \div \frac{1}{3} = 5 \times 3 = 15$

$4 \times \frac{2}{7} = \frac{8}{7}$

$6 \div \frac{3}{7} = 6 \times \frac{7}{3} = \frac{42}{3} = 14$

$\frac{7}{9} \times 2 = \frac{14}{9}$

$\frac{11}{3} \div 5 = \frac{11}{3} \times \frac{1}{5} = \frac{11}{15}$

$\frac{14}{5} \times 5 = \frac{70}{5} = 14$

$\frac{21}{3} \div 2 = \frac{21}{3} \times \frac{1}{2} = \frac{21}{6} = \frac{7}{2}$

$\frac{27}{13} \times 2 = \frac{54}{13} = 4$
