[tex] \frac{1}{6} + \frac{1}{3} = \frac{1}{6} + \frac{2}{6} = \frac{3}{6} = 0.5[/tex]
[tex] \frac{3}{7} - \frac{1}{3} = \frac{9}{21} - \frac{7}{21} = \frac{2}{21} = 0.(095238)[/tex]
[tex] \frac{5}{6} \div \frac{10}{3} = \frac{5}{6} \times \frac{3}{10} = \frac{1}{4} = 0.25[/tex]
[tex] \frac{27}{7} \times 2 \frac{1}{3} = \frac{27}{7} \times \frac{7}{3} = 9[/tex]
