a) $\frac{4}{6}$ = $\frac{2}{3}$ $\frac{11}{22}$ = $\frac{1}{2}$ b) $\frac{12}{36}$ = $\frac{1}{3}$ |
$\frac{12}{8}$ = $\frac{3}{2}$ $\frac{36}{10}$ = $\frac{18}{5}$ $\frac{75}{300}$ = $\frac{1}{4}$ |
$\frac{15}{25}$ = $\frac{3}{5}$ $\frac{75}{36}$ = $\frac{25}{12}$ $\frac{15}{35}$ = $\frac{3}{7}$ |
