[tex] \frac{22}{3} - \frac{13}{9} \div \frac{26}{12} = \frac{22}{3} - \frac{13}{9} \times \frac{12}{26} = \frac{22}{3} - \frac{1}{3} \times \frac{4}{2} = \frac{22}{3} - \frac{1}{3} \times 2 = \frac{22}{3} - \frac{2}{3} = \frac{20}{3} = 6 \frac{2}{3} [/tex]
[tex]b)3 \frac{2}{15} + \frac{1}{6} \div ( \frac{1}{3} ) ^{2} = \frac{47}{15} + \frac{1}{6} \div \frac{1}{9} = \frac{47}{15} + \frac{1}{6} \times 9 = \frac{47}{15} + \frac{1}{2} \times 3 = \frac{139}{30} = 4 \frac{19}{30} \\ \\ c) \frac{2}{13} - \frac{1}{26} + ( \frac{2}{13} )^{24} \div ( \frac{2}{13} )^{23} = \frac{2}{3} - \frac{1}{26} + \frac{2}{3} = \frac{7}{26} \\ \\ d)( \frac{4}{10} )^{34} \div ( { \frac{2}{5}) }^{33} = \frac{2}{5} [/tex]
