Charlotte og Charlie lagde 12 liter saft

a) $2\cdot\frac{1}{4}=\frac{2}{4}=\frac{1}{2}$	b) $3\cdot\frac{1}{7}=\frac{3}{7}$	c) $2\cdot\frac{3}{8}=\frac{6}{8}=\frac{3}{4}$
d) $5\cdot\frac{2}{5}=\frac{10}{5}=2$	e) $\frac{1}{6}\cdot9=\frac{9}{6}=1\frac{3}{6}=1\frac{1}{2}$	f) $12\cdot\frac{3}{14}=\frac{36}{14}=2\frac{8}{14}=2\frac{4}{7}$

$\frac{1}{2}$ mil = 5 km

a) $\frac{2}{4}\cdot\frac{1}{3}=\frac{2}{8}=\frac{1}{4}$	b) $\frac{2}{7}\cdot\frac{1}{3}=\frac{2}{21}$	c) $\frac{3}{8}\cdot\frac{1}{3}=\frac{3}{24}=\frac{1}{8}$
d) $\frac{4}{5}\cdot\frac{2}{3}=\frac{8}{15}$	e) $\frac{4}{6}\cdot\frac{1}{4}=\frac{4}{24}=\frac{1}{6}$	f) $\frac{2}{3}\cdot\frac{3}{4}=\frac{6}{12}=\frac{1}{2}$
