Приведение к общему знаменателю

Теперь приведем каждую дробь к знаменателю 60: $$\frac{29}{30} = \frac{29 \times 2}{30 \times 2} = \frac{58}{60} - я$$ $$\frac{1}{5} = \frac{1 \times 12}{5 \times 12} = \frac{12}{60} - u$$ $$\frac{5}{12} = \frac{5 \times 5}{12 \times 5} = \frac{25}{60} - т$$ $$\frac{4}{5} = \frac{4 \times 12}{5 \times 12} = \frac{48}{60} - e$$ $$\frac{1}{15} = \frac{1 \times 4}{15 \times 4} = \frac{4}{60} - в$$ $$\frac{1}{6} = \frac{1 \times 10}{6 \times 10} = \frac{10}{60} - л$$ $$\frac{2}{3} = \frac{2 \times 20}{3 \times 20} = \frac{40}{60} - г$$ $$\frac{1}{60} - д$$ $$\frac{9}{20} = \frac{9 \times 3}{20 \times 3} = \frac{27}{60} - н$$ $$\frac{11}{20} = \frac{11 \times 3}{20 \times 3} = \frac{33}{60} - и$$ $$\frac{1}{4} = \frac{1 \times 15}{4 \times 15} = \frac{15}{60} - c$$ $$\frac{1}{12} = \frac{1 \times 5}{12 \times 5} = \frac{5}{60} - у$$ $$\frac{7}{10} = \frac{7 \times 6}{10 \times 6} = \frac{42}{60} - р$$ $$\frac{7}{12} = \frac{7 \times 5}{12 \times 5} = \frac{35}{60} - к$$
