Question

Хелп, я сижу 2 часа над этим!

Answer 1

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

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