[tex] \frac{1}{8} = \frac{125}{1000} = 12.5\%[/tex]
1. 12.5% - 8% = 4.5%
2.
[tex] \frac{5}{6} + \frac{2}{3} - \frac{1}{4} = \frac{10}{12} + \frac{8}{12} - \frac{3}{12} = \frac{18}{12} - \frac{3}{12} = \frac{15}{12} = 1 \frac{1}{4} [/tex]
[tex] \frac{3}{8} - \frac{1}{5} + \frac{1}{2} \\ \frac{3}{8} = \frac{375}{1000} = 37.5 \\ \frac{1}{5} = \frac{2}{10} = 0.2 \\ \frac{1}{2} = \frac{5}{10} = 0.5[/tex]
3. 37.5-0.2+0.5 = 37.3+0.5 = 37.8
