2) Решите примеры. Выполните нужное преобразование дроби в ответе.

Решим примеры:

1. $$\frac{1}{2} + \frac{1}{2} = \frac{1+1}{2} = \frac{2}{2} = 1$$
2. $$\frac{1}{4} + \frac{3}{4} = \frac{1+3}{4} = \frac{4}{4} = 1$$
3. $$\frac{5}{6} - \frac{1}{6} = \frac{5-1}{6} = \frac{4}{6} = \frac{2}{3}$$
4. $$\frac{5}{8} + \frac{3}{8} = \frac{5+3}{8} = \frac{8}{8} = 1$$
5. $$\frac{1}{10} + \frac{3}{10} = \frac{1+3}{10} = \frac{4}{10} = \frac{2}{5}$$
6. $$\frac{7}{9} - \frac{4}{9} = \frac{7-4}{9} = \frac{3}{9} = \frac{1}{3}$$
7. $$\frac{2}{3} + \frac{2}{3} = \frac{2+2}{3} = \frac{4}{3} = 1\frac{1}{3}$$
8. $$\frac{9}{10} - \frac{3}{10} = \frac{9-3}{10} = \frac{6}{10} = \frac{3}{5}$$
