Answer 1

$\frac{4}{5} : 7 = \frac{4}{5} : \frac{7}{1} = \frac{4}{5} * \frac{1}{7} = \frac{4}{5*7} = \frac{4}{35}$

$\frac{9}{10} : 2 = \frac{9}{10} : \frac{2}{1} = \frac{9}{10} * \frac{1}{2} = \frac{9}{10*2} = \frac{9}{20} = 0,45$

$\frac{2}{7} : 7 = \frac{2}{7} : \frac{7}{1} = \frac{2}{7} * \frac{1}{7} = \frac{2}{7*7} = \frac{2}{49}$

$\frac{8}{11} : 4 = \frac{8}{11} : \frac{4}{1} = \frac{8}{11} * \frac{1}{4} = \frac{8}{11*4} = \frac{2}{11}$

$\frac{3}{22} : 2 = \frac{3}{22} : \frac{2}{1} = \frac{3}{22} * \frac{1}{2} = \frac{3}{22*2} = \frac{3}{44}$

$\frac{5}{6} : 6 = \frac{5}{6} : \frac{6}{1} = \frac{5}{6} * \frac{1}{6} = \frac{5}{6*6} = \frac{5}{36}$

$\frac{6}{13} : 3 = \frac{6}{13} : \frac{3}{1} = \frac{6}{13} * \frac{1}{3} = \frac{6}{13*3} = \frac{2}{13}$

$\frac{15}{15} : 7 = 1 : 7 = \frac{1}{7}$

Answer 2

Ответ:

Пошаговое объяснение:

$\frac{4}{5}:7=\frac{4*1}{5*7}=\frac{4}{35}$

$\frac{3}{22}:2=\frac{3*1}{22*2}=\frac{3}{44}$

$\frac{9}{10}:2=\frac{9*1}{10*2}=\frac{9}{20}$

$\frac{5}{6}:6=\frac{5*1}{6*6}=\frac{5}{36}$

$\frac{2}{7}:7=\frac{2*1}{7*7}=\frac{2}{49}$

$\frac{6}{13}:3=\frac{6*1}{13*3}=\frac{2}{13}$

$\frac{8}{11}:4=\frac{8*1}{11*4}=\frac{2}{11}$

$\frac{15}{15}:7 =1:7=\frac{1}{7}$
