Answer 1

3)

$\frac{1}{12} u \frac{1}{6} = \frac{1}{12} u \frac{2}{12} \\ \\ \frac{1}{10} u \frac{2}{15} = \frac{3}{30} u \frac{4}{30}$

1)

$\frac{1}{4} u \frac{1}{6} = \frac{3}{12} u \frac{2}{12 } \\ \\ \frac{1}{8} u \frac{1}{6} = \frac{3}{24} u \frac{4}{24}$

2)

$\frac{2}{5} u \frac{7}{10} = \frac{4}{10} u \frac{7}{10 } \\ \\ \frac{2}{3} u \frac{3}{4} = \frac{8}{12} u \frac{9}{12}$

удачи!!!!
