Answer 1

1. г)
$\frac{6}{11} \div 3 = \frac{6}{11} \times \frac{1}{3} = \frac{6 \times 1}{11 \times 3} = \\ = \frac{2 \times 1}{11 \times 1} = \frac{2}{11} . \\ \\ \\otwet: \frac{2}{11}$




2. д)
$1 \: \frac{2}{7} \div 1 = \frac{9}{7} \div 1 = \frac{9}{7} \times \frac{1}{1} = \\ \\ = \frac{9 \times 1}{7 \times 1} = \frac{9}{7} \\ \\ \\ otwet \: \frac{9}{7}$

Answer 2

Г)
$\frac{6}{11} \div 3 = \frac{6}{11} \div \frac{1}{3} = \frac{2}{11}$
д)
$1 \frac{2}{7} \div 1 = \frac{9}{7} \div 1 = 1\frac{2}{7}$
е)
$1 \div \frac{9}{19} = \frac{19}{9} = 2 \frac{1}{9}$
