[tex] \frac{4}{7} \div \frac{22}{7} = \frac{4}{7} \times \frac{7}{22} = \frac{28}{154} = \frac{2}{11} [/tex]
h)
[tex] \frac{16}{3} \div \frac{28}{9} = \frac{16}{3} \times \frac{9}{28} = \frac{144}{84} = \frac{12}{7} [/tex]
a)
[tex] \frac{31}{12} \div \frac{31}{24} = \frac{31}{12} \times \frac{24}{31} = 2[/tex]
c)
[tex] \frac{55}{24} \times \frac{24}{77} + \frac{2}{7} = 5 \times \frac{1}{7} + \frac{2}{7} = \frac{5}{7} + \frac{2}{7} = \frac{7}{7} = 1[/tex]
