Хелп, я сижу 2 часа над этим!

Пошаговое объяснение:

1) $\frac{6}{25} : \frac{3}{5} = \frac{6}{25} * \frac{5}{3} = \frac{30}{75} =\frac{2}{5} =0,4$

2) $\frac{8}{15} : \frac{20}{21} = \frac{8}{15} * \frac{21}{20} = \frac{168}{300} = \frac{56}{100} =0,56$

3) $\frac{14}{15} : \frac{28}{33} = \frac{14}{15} * \frac{33}{28} = \frac{462}{420} = 1\frac{1}{10} =1,1$

4) $\frac{39}{43} : \frac{13}{43} = \frac{39}{43} *\frac{43}{13} =3$

5) $\frac{27}{32} : \frac{9}{16} = \frac{27}{32} * \frac{16}{9} = \frac{3}{2} = 1,5$

6) $\frac{21}{22} : \frac{7}{18} = \frac{21}{22} * \frac{18}{7} = \frac{3*9}{11} = \frac{27}{11}$

7) $\frac{2}{7} : \frac{16}{35} = \frac{2}{7} * \frac{35}{16} = \frac{5}{8} = 0,625$

8) $\frac{44}{45} : \frac{11}{18} = \frac{44}{45} * \frac{18}{11} = \frac{4*2}{3} = \frac{8}{3} = 2\frac{2}{3}$
