$\frac{18}{30} = \frac{3}{5} = \frac{18}{30} \\ \frac{15}{18} = \frac{5}{6} = \frac{25}{30}$

2.

$\frac{28}{40} = \frac{7}{10} = \frac{63}{90} \\ \frac{10}{45} = \frac{2}{9} = \frac{20}{90}$

3.

$\frac{49}{105} = \frac{7}{15} = \frac{28}{60} \\ \frac{27}{36} = \frac{3}{4} = \frac{45}{60}$

4.

$\frac{16}{90} = \frac{8}{45} = \frac{16}{90} \\ \frac{15}{50} = \frac{3}{10} = \frac{27}{90}$

5.

$\frac{10}{20} = \frac{1}{2} = \frac{15}{30} \\ \frac{8}{24} = \frac{1}{3} = \frac{10}{30} \\ \frac{9}{45} = \frac{1}{5} = \frac{6}{30}$

6.

$\frac{22}{44} = \frac{1}{2} = \frac{10}{20} \\ \frac{24}{30} = \frac{4}{5} = \frac{16}{20} \\ \frac{27}{36} = \frac{3}{4} = \frac{15}{20}$
