[tex]1 \frac{6}{12} = 1 \frac{1}{2} [/tex]
[tex]a. \: 1 \frac{2}{5} \times 1 \frac{1}{9} = \frac{7}{5} \times \frac{10}{9} = \frac{14}{9} = 1 \frac{5}{9} [/tex]
[tex]b. \: \: 1 \frac{5}{6} \div 1 \frac{2}{9} = \frac{11}{6} \div \frac{11}{9} = \frac{11}{6} \times \frac{9}{11} = \frac{9}{6} = 1 \frac{3}{6} = 1 \frac{1}{2} [/tex]
