Решим данные примеры:

1. $$ -4.3 $$
2. $$ -7.2 + 0.8 = -6.4 $$
3. $$ -4.6 + 4.7 = 0.1 $$
4. $$ -2.1 + (-2.7) = -2.1 - 2.7 = -4.8 $$
5. $$ -4.3 + (-5.4) = -4.3 - 5.4 = -9.7 $$
6. $$ 5.33 + (-2.8) = 5.33 - 2.8 = 2.53 $$
7. $$ -\frac{1}{4} + \frac{1}{3} = -\frac{3}{12} + \frac{4}{12} = \frac{1}{12} $$
8. $$ -\frac{1}{6} + (-\frac{1}{3}) = -\frac{1}{6} - \frac{1}{3} = -\frac{1}{6} - \frac{2}{6} = -\frac{3}{6} = -\frac{1}{2} $$
9. $$ 2\frac{2}{5} + (-3\frac{3}{5}) = \frac{12}{5} - \frac{18}{5} = -\frac{6}{5} = -1\frac{1}{5} $$
10. $$ 6\frac{1}{3} + (-1\frac{7}{12}) = \frac{19}{3} - \frac{19}{12} = \frac{76}{12} - \frac{19}{12} = \frac{57}{12} = \frac{19}{4} = 4\frac{3}{4} $$
11. $$ -5\frac{3}{4} + 6\frac{1}{3} = -\frac{23}{4} + \frac{19}{3} = -\frac{69}{12} + \frac{76}{12} = \frac{7}{12} $$
