Answer 1

1)

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

2)

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

3)

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

4)

$26 \div 3 \frac{1}{4} \times \frac{1}{1} = 26 \div \frac{13}{4} \times \frac{1}{1} = 26 \times \frac{4}{13} \times \frac{1}{1} = 8$

5)

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

6)

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