a)
[tex] \frac{5}{8} [/tex]
[tex] \frac{1}{8} [/tex]
[tex] \frac{5}{8} - \frac{1}{8} = \frac{4}{8} [/tex]
b)
[tex] \frac{6}{10} [/tex]
[tex] \frac{3}{10} [/tex]
[tex] \frac{6}{10} - \frac{3}{10} = \frac{3}{10} [/tex]
c)
[tex] \frac{2}{3} [/tex]
[tex] \frac{1}{3} [/tex]
[tex] \frac{2}{3} - \frac{1}{3} = \frac{1}{3} [/tex]
