[tex] - 1\frac{2}{5} \div ( - 2.8 ) = - \frac{7}{5} \times ( - \frac{10}{28} ) = \frac{2}{4} = \frac{1}{2} = 0.5[/tex]
[tex] - 1 \frac{2}{5} \div ( - 2.8) = - 1 \frac{2}{5} \div (- 2 \frac{4}{5}) = - \frac{7}{5} \div ( - \frac{14}{5} ) = - \frac{7}{5} \times ( - \frac{5}{14} = \frac{98}{25} =3 \frac{23}{25} [/tex]
