[tex]2.88 - 2.88x \frac{1}{6} = 2 \frac{22}{25} - \frac{72}{25} \times \frac{1}{6} = 2 \frac{22}{25} - \frac{12}{25} = 2 \frac{2}{5} = 2.4[/tex]

[tex]2 \frac{22}{25} - 2 \frac{2}{5} \times \frac{1}{3} = 2 \frac{22}{25} - \frac{12}{5} \times \frac{1}{3} = 2 \frac{22}{25} - \frac{4}{5} = 2 \frac{22}{25} - \frac{20}{25} = 2\frac{2}{25} = 2.08[/tex]
