Answer 1

А) 6/7:2=6/7*1/2=6/14=3/7
б)1/7:2=1/7*1/2=1/14
в)15/11:5=15/11*1/5=3/11
г)17/11:5=17/11*1/5=17/55

Answer 2

Вычислить* а,б,в,г
$\frac{6}{7} \div 2 = \frac{6}{7} \times \frac{1}{2} = \frac{3}{7} \\ \frac{1}{7} \div 2 = \frac{1}{7} \times \frac{1}{2} = \frac{1}{14} \\ \frac{15}{11} \div 5 = \frac{15}{11} \times \frac{1}{5} = \frac{3}{11} \\ \frac{17}{11} \div 5 = \frac{17}{11} \times \frac{1}{5} = \frac{17}{55}$
