Answer 1

$(1)2 \frac{1}{7} - 1\frac{2}{5} = \frac{15}{7} - \frac{7}{5} = \frac{26}{35} \\ (2)1 \frac{7}{9} \div 5 \frac{1}{3} = \frac{16}{9} \div \frac{16}{3} = \frac{16}{9} \times \frac{3}{16} = \frac{1}{3} \\ (3) \frac{3}{7} \div 6 = \frac{3}{7} \times \frac{1}{6} = \frac{1}{7} \times \frac{1}{2} = \frac{1}{14} \\ (4) \frac{6}{25} \div \frac{3}{5} = \frac{6}{25} \times \frac{5}{3} = \frac{2}{25} \times 5 = \frac{2}{5}$
