Answer 1

2|3 × 6|7 = 6÷3 = 2|1(сократили на 3) × 2|7 = 4|7

Answer 2

№504

1) $\frac{2}{3} * \frac{6}{7} = \frac{4}{7}$

2) $\frac{4}{7} * \frac{21}{40} = \frac{12}{10} = 1,2$

3) $\frac{27}{32} * \frac{8}{9} = \frac{3}{4} = 0,75$

4) $\frac{5}{11} * \frac{22}{25} = \frac{2}{5} = 0,4$

5) $\frac{8}{35} * \frac{5}{12} = \frac{2}{21}$

№505

1) $\frac{7}{9} * \frac{6}{1} = \frac{14}{3} = 4\frac{2}{3}$

2) $\frac{4}{1} * \frac{3}{20} = \frac{3}{5} = 0,6$

3) $\frac{5}{6} * \frac{3}{1} = \frac{5}{2} = 2,5$

4) $\frac{14}{1} * \frac{7}{16} = \frac{49}{8} = 6,125$

5) $\frac{27}{1} * \frac{2}{9} = \frac{6}{1} = 6$
