1. а) \[\frac{5}{75} = \frac{5 \div 5}{75 \div 5} = \frac{1}{15}\]

2. б) \[\frac{16}{20} = \frac{16 \div 4}{20 \div 4} = \frac{4}{5}\]

3. в) \[\frac{14}{35} = \frac{14 \div 7}{35 \div 7} = \frac{2}{5}\]

4. г) \[\frac{21}{39} = \frac{21 \div 3}{39 \div 3} = \frac{7}{13}\]

5. д) \[\frac{10}{60} = \frac{10 \div 10}{60 \div 10} = \frac{1}{6}\]

6. е) \[\frac{28}{84} = \frac{28 \div 28}{84 \div 28} = \frac{1}{3}\]

7. ж) \[\frac{56}{72} = \frac{56 \div 8}{72 \div 8} = \frac{7}{9}\]

8. з) \[\frac{20}{25} = \frac{20 \div 5}{25 \div 5} = \frac{4}{5}\]

9. и) \[\frac{120}{180} = \frac{120 \div 60}{180 \div 60} = \frac{2}{3}\]

10. к) \[\frac{207}{243} = \frac{207 \div 9}{243 \div 9} = \frac{23}{27}\]
