Помогите пожалуйста!

Answer 1

#1

$\frac{6}{90} = \frac{6}{6 \times 15} = \frac{1}{15} \\ \\ \frac{5}{20} = \frac{1}{4}$

$\frac{10}{12} = \frac{5}{6} \\ \\ \frac{25}{35} = \frac{5}{7} \\ \\ \frac{25}{60} = \frac{5}{12}$

$\frac{28}{35} = \frac{4}{5}$

$\frac{42}{63} = \frac{6 \times 7}{9 \times 7} = \frac{2}{3}$

#2

$\frac{2}{5} = \frac{14}{35} \: and \: \frac{7}{35}$

$\frac{11}{30} \: and \: \frac{14}{25} \\ \frac{55}{150} \: and \: \frac{84}{150}$

$\frac{1}{12} = \frac{4}{48} \: and \: \frac{5}{48}$

#3

$\frac{5}{12} < \frac{8}{12}$

$\frac{4}{17} = \frac{12}{51} < \frac{16}{51}$

$\frac{13}{13} = 1 > \frac{4}{9}$

$\frac{12}{21} = \frac{4}{7} = \frac{4}{7}$

$\frac{23}{23 } = 1 < \frac{56}{55}$
