a) \(\frac{3}{5} \div \frac{6}{7} = \frac{3}{5} \times \frac{7}{6} = \frac{21}{30} = \frac{7}{10}\)
b) \(\frac{1}{6} \div \frac{7}{12} = \frac{1}{6} \times \frac{12}{7} = \frac{2}{7}\)
c) \(\frac{1}{3} \div \frac{2}{9} = \frac{1}{3} \times \frac{9}{2} = \frac{3}{2}\)
d) \(\frac{1}{9} \div \frac{1}{7} = \frac{1}{9} \times \frac{7}{1} = \frac{7}{9}\)
e) \(\frac{7}{7} \div \frac{7}{3} = \frac{7}{7} \times \frac{3}{7} = \frac{3}{7}\)
f) \(\frac{15 \frac{8}{3}}{2} = 15 \frac{8}{3} \div 2 = \frac{46}{3}\)
g) \(\frac{7}{9} \div \frac{1}{3} = \frac{7}{9} \times \frac{3}{1} = \frac{7}{3}\)
h) \(\frac{5}{8} \div \frac{1}{2} = \frac{5}{8} \times \frac{2}{1} = \frac{5}{4}\)
