1. 5/3 - 2/6 = 2. 5/6 - 3/12 = 3. 6/2 - 2/7 =

1.
[tex] = \frac{5}{3} - \frac{2}{6} \\ = \frac{10}{6} - \frac{2}{6} \\ = \frac{8}{6} \\ = \frac{4}{3} [/tex]
2.
[tex] = \frac{5}{6} - \frac{3}{12} \\ = \frac{10 - 3}{12} \\ = \frac{7}{12} [/tex]
3.
[tex] = \frac{6 }{2} - \frac{2}{7} \\ = 3 - \frac{2}{7} \\ = \frac{7}{7} - \frac{2}{7} \\ = \frac{7 - 2}{7} \\ = \frac{5}{7} [/tex]
