Answer 2

Răspuns:

$a)\frac{2}{7}:\frac{3}{5} =\frac{2}{7}*\frac{5}{3} =\frac{10}{21} \\\\b)3\frac{1}{3}:1 \frac{1}{9}=\frac{10}{3}:\frac{10}{9}=\frac{10}{3}*\frac{9}{10}=\frac{9}{3}=3\\\\c)\frac{65}{8}:4\frac{1}{16} =\frac{65}{8}:\frac{65}{16}=\frac{65}{8}*\frac{16}{65}=\frac{16}{8}=2\\\\d)1:3\frac{1}{7}=1:\frac{22}{7}=1*\frac{7}{22} =\frac{7}{22}$

Sper că te-am ajutat!
