Помогите пожалуйста,номер 449.

Решите задачу:

$1) 6: \frac{7}{9} = \frac{6*9}{7} = \frac{54}{7}=7 \frac{5}{7}$

$2)16: \frac{4}{11} = \frac{16*11}{4} =4*11=44$

$3)13: \frac{26}{29} = \frac{13*29}{13*2} = \frac{29}{2} =14 \frac{1}{2} =14,5$

$4) \frac{7}{9} :5= \frac{7}{9*5}= \frac{7}{45}$

$5) \frac{9}{16} :6= \frac{9}{16*6} = \frac{3}{16*2} = \frac{3}{32}$

$6)1 \frac{5}{9} :1 \frac{8}{27}= \frac{14*27}{9*35} = \frac{14*3}{35} = \frac{42}{35} =1 \frac{7}{35} =1\frac{1}{5} =1,2$
