1.
[tex] = 3 \frac{2}{7} \div 4 + \frac{1}{2} \\ = \frac{22}{7} \times \frac{1}{4} + \frac{1}{2} \\ = \frac{22}{28} + \frac{1}{2} \\ = \frac{11}{14} + \frac{1}{2} \\ = \frac{11 + 7}{14} \\ = \frac{9}{7} [/tex]
2.
[tex] = 2 \div \frac{6}{7} + 3 \frac{1}{4} \\ = 2 \times \frac{7}{6} + \frac{13}{4} \\ = \frac{7}{3} + \frac{13}{4} \\ = \frac{28 + 39}{12} \\ = \frac{67}{12} [/tex]
3.
[tex] = \frac{5}{7} \div \frac{2}{4} - \frac{1}{6} \\ = \frac{5}{7} \times 2 - \frac{1}{6} \\ = \frac{10}{7} - \frac{1}{6} \\ = \frac{60 - 7}{42} \\ = \frac{53}{42} [/tex]
4.
[tex] = \frac{2}{7} - \frac{1}{9} \div \frac{2}{9} \\ = \frac{2}{7} - \frac{1}{9} \times \frac{9}{2} \\ = \frac{2}{7} - \frac{1}{9} \\ = \frac{18 - 7}{63} \\ = \frac{11}{63} [/tex]
