Answer 1

Ответ:

$1) 3 \frac{1}{3 } \div \frac{2}{3} \times \frac{1}{5} = \frac{10 \times 3 \times 1}{3 \times 2 \times 5} = 1$

$2) \frac{4}{5} \times 2 \frac{1}{2} \div 6 = \frac{4 \times 5 \times 1}{5 \times 2 \times 6} = \frac{1}{3}$

$3) 3 \frac{1}{5} \times \frac{5}{8} \div \frac{2}{7} = \frac{16 \times 5 \times 7}{5 \times 8 \times 2} = 7$

$4) 26 \div 3\frac{1}{4} \times \frac{1}{16} = \frac{26 \times 4 \times 1}{13 \times 16} = \frac{1}{2}$

$5) 4 \frac{1}{8} \times \frac{6}{11} \div 2 \frac{1}{4} = \frac{33 \times 6 \times 4}{8 \times 11 \times 9} = \frac{3 \times 2 \times 1}{2 \times 1 \times 3 } = 1$

$6) 1 \frac{1}{7} \times \frac{3}{4} \div \frac{3}{10} = \frac{8 \times 3 \times 10}{7 \times 4 \times 3} = \frac{20}{7} = 2 \frac{6}{7}$
