Всё ниже.

Пошаговое объяснение:

$\frac{35}{255} \frac{19}{255}$

$\frac{57}{210} \frac{57}{221}$

$\frac{2}{136} = \frac{1}{68} \\ \frac{2}{136} = \frac{2 \div 2}{136 \div 2} = \frac{1}{68}$

$\frac{72}{250} < \frac{3}{10} \\ \frac{72 \div 2}{250 \div 2} = \frac{36}{125} \\ \frac{3 \times 12}{10 \times 12} = \frac{36}{120} \\ \frac{36}{125} < \frac{36}{120}$

$\frac{5}{100} \frac{1}{25} \\ \frac{1 \times 4}{25 \times 4} = \frac{4}{100} \\ \frac{5}{100} \frac{4}{100}$

$\frac{50}{210} \frac{5}{22} \\ \frac{50 \div 10}{210 \div 10} = \frac{5}{21} \\ \frac{5}{21} \frac{5}{22}$

$- \frac{2}{13} < - \frac{10}{68} \\ - \frac{2 \times 68}{13 \times 68} = - \frac{136}{884} \\ - \frac{10 \times 13}{68 \times 13} = - \frac{130}{884} \\ - \frac{136}{884} < - \frac{130}{884}$

$- \frac{2}{136} - \frac{7}{408} \\ - \frac{2 \times 3}{136 \times 3} = - \frac{ 6}{408} \\ - \frac{6}{408} - \frac{ 7}{408}$

Удачи☘.
