Answer 2

Пошаговое объяснение:

$6)\; \; \frac{2}{3}=\frac{2\cdot 7}{3\cdot 7}=\frac{14}{21}\; \; ;\; \; \frac{1}{7}= \frac{1\cdot 3}{7\cdot 3}= \frac{3}{21}\\\\\frac{3}{5}=\frac{3\cdot 6}{5\cdot 6}=\frac{18}{30}\; \; ;\; \;  \frac{1}{6}=\frac{1\cdot 5}{6\cdot 5}=\frac{5}{30}\\\\\frac{5}{11}=\frac{5\cdot 4}{11\cdot 4}=\frac{20}{44}\; \; ;\; \;  \frac{3}{4}=\frac{3\cdot 11}{4\cdot 11}=\frac{33}{44}\\\\\frac{1}{6}=\frac{1\cdot 7}{6\cdot 7}=\frac{7}{42}\; \; ,\; \; \frac{1}{7}=\frac{1\cdot 6}{7\cdot 6}=\frac{6}{42}$

$7)\; \; \frac{5}{6}=\frac{5\cdot 2}{6\cdot 2}=\frac{10}{12}\; \; ;\; \; \frac{7}{12}=\frac{7}{12}\\\\\frac{5}{8}=\frac{5\cdot 2}{8\cdot 2}=\frac{10}{16}\; \; ;\; \; \frac{3}{16}=\frac{3}{16}\\\\\frac{3}{4}=\frac{3\cdot 5}{4\cdot 5}=\frac{15}{20}\; \; ;\; \; \frac{1}{20}=\frac{1}{20}\\\\ \frac{2}{18}= \frac{2}{18}\; \; ;\; \; \frac{5}{6}=\frac{5\cdot 3}{6\cdot 3}=\frac{15}{18}$
