[tex](3 - \frac{1}{5} ) \div (2 - \frac{1}{2} )[/tex]
[tex] = ( \frac{15}{5} - \frac{1}{5} ) \div ( \frac{4}{2} - \frac{1}{2} )[/tex]
[tex] = \frac{15 - 1}{5} \div \frac{4 - 1}{2} [/tex]
[tex] = \frac{14}{5} \div \frac{3}{2} [/tex]
[tex] = \frac{14}{5} \times \frac{2}{3} [/tex]
[tex] = \frac{14 \times 2}{5 \times 3} [/tex]
[tex] = \frac{28}{15} [/tex]
