Найдите частное: 1)1/5:1/6 2)1/7:1/77 3)1/13:4/39 4)7/3:7/4

Лексия $1) \frac{1}{5} : \frac{1}{6} = \frac{1}{5}*\frac{6}{1} =\frac{6}{5}=1,2 \\ 2) \frac{1}{7}:\frac{1}{77}=\frac{1}{7}*\frac{77}{1}=\frac{77}{7}=11 \\ 3)\frac{1}{13}:\frac{4}{39}=\frac{1}{13}*\frac{39}{4}=\frac{39}{13*4}=\frac{3}{1*4}=0,75 \\ 4) \frac{7}{3}:\frac{7}{4}= \frac{7}{3}*\frac{4}{7}=\frac{4}{3}=1\frac{1}{3}$
