Question 1

Question 2

18/30 и 15/18
$\frac{15}{18} = \frac{3 \times 5}{6 \times 3} = \frac{5}{6} = \frac{5 \times 5}{6 \times6} = \frac{25}{30} \\ \frac{25}{30} = \frac{18}{30} \\ \\$

28/40 и 10/45
$\frac{28}{40} = \frac{7 \times 4}{4 \times 10} = \frac{7}{10} = \frac{7}{5 \times 2} = \frac{7 \times 9}{5 \times 2 \times 9} = \frac{63}{90} \\ \frac{10}{45} = \frac{5 \times 2}{9 \times 5} = \frac{5 \times 2 \times 2}{9 \times 5 \times 2} = \frac{20}{90}$

49/105 и 27/36
$\frac{49}{105} = \frac{7 \times 7}{5 \times 3 \times 7} = \frac{7}{5 \times 3} = \frac{7 \times 4}{ 5\times 3 \times 4} = \frac{28}{60} \\ \frac{27}{36} = \frac{9 \times 3}{4 \times 3 \times 3} = \frac{9}{4 \times 3} = \frac{9 \times 5}{4 \times 3 \times 5} = \frac{45}{60}$

60/90 и 15/50
$\frac{60}{90} = \frac{3 \times 2 \times 10}{3 \times 3 \times 10} = \frac{2 \times 10}{3 \times 10} = \frac{20}{30} \\ \frac{15}{50} = \frac{5 \times 3}{5 \times 10} = \frac{3}{10} = \frac{3 \times 3}{10 \times 3} = \frac{9}{30}$

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

6) извини, у меня глаза болят, не смогу(
