A)
[tex] - 5.125 - ( - \frac{1}{8} ) = - 5.125 + \frac{1}{8} = - 5.125 + 0.125 = - 5[/tex]
B)
[tex]2 \frac{1}{3} + ( - 6.6) = \frac{7}{3} - 6 \frac{3}{5} = \frac{7}{3} - \frac{33}{5} = \frac{35}{15} - \frac{99}{15} = - \frac{64}{15} = - 4 \frac{4}{15} [/tex]
C)
[tex]7.5 \div ( - 0.25) = 7 \frac{1}{2} \div ( - \frac{1}{4} ) = \frac{15}{2} \times ( - 4) = - 30[/tex]
D)
[tex]6 \div ( - 1 \frac{1}{3} ) = 6 \div ( - \frac{4}{3} ) = 6 \times ( - \frac{3}{4} ) = - \frac{18}{4} = - 4 \frac{2}{4} = - 4 \frac{1}{2} [/tex]
E)
[tex]( - 0.05) \times ( - 6000) = ( - \frac{5}{100} ) \times ( - 6000) = \frac{1}{20} \times 6000 = 300[/tex]
