Answer 1

$4 \div 2 \frac{2}{5} = 2 \times \frac{2}{5} = \frac{4}{5}$

$5 \frac{5}{7} \div 25 = \frac{40}{7} \times \frac{1}{25} = \frac{8}{7} \times \frac{1}{5} = \frac{8}{35}$

$4 \frac{2}{7} \div \frac{5}{7} = \frac{30}{7} \times \frac{7}{5} = 30 \frac{1}{5} = 6$

$6 \frac{2}{3} \div 2 \frac{4}{7} = \frac{20}{3} \times \frac{1}{2} \times \frac{4}{7} = \frac{10}{3} \times \frac{4}{7} = \frac{40}{21}$

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