[tex]4 \frac{3}{4} \times (2.57 - 1.5) + 4.75 \times (1 \frac{1}{2} - 2.57) = \frac{19}{4} \times 1.07 + \frac{19}{4} \times ( \frac{3}{2} - \frac{257}{100} ) = \frac{19}{4} \times \frac{107}{100} + \frac{19}{4} \times ( - \frac{107}{100} ) = \frac{19}{4} \times \frac{107}{100} - \frac{19}{4} \times \frac{107}{100} = 0[/tex]
[tex] \frac{1}{2} = 0.5 \\ \frac{3}{4} = 0.75 \\ \frac{1}{8} = 0.125 \\ \frac{1}{5} = 0.2 \\ \frac{2}{5} = 0.4 \\ \frac{1}{4} = 0.25 \\ \frac{3}{25} = 0.12[/tex]
