Answer 2

Let's calculate each of these expressions step by step:

1. $2 - \frac{2}{7} = \frac{14}{7} - \frac{2}{7} = \frac{12}{7}.$

2. $4 \frac{3}{5} - 1 \frac{2}{15} = \frac{23}{5} - \frac{17}{15} = \frac{69}{15} - \frac{17}{15} = \frac{52}{15}.$

3. $3 - 2 \frac{1}{3} = 3 - \frac{7}{3} = \frac{9}{3} - \frac{7}{3} = \frac{2}{3}.$

4. $12 \frac{14}{13} - 5 \frac{10}{13} = \frac{170}{13} - \frac{70}{13} = \frac{100}{13}.$

5. $(3 + \frac{4}{7}) - 2 = \frac{21}{7} + \frac{4}{7} - 2 = \frac{25}{7} - 2 = \frac{25}{7} - \frac{14}{7} = \frac{11}{7}.$

So, the results are:

1. $2 - \frac{2}{7} = \frac{12}{7}.$
2. $4 \frac{3}{5} - 1 \frac{2}{15} = \frac{52}{15}.$
3. $3 - 2 \frac{1}{3} = \frac{2}{3}.$
4. $12 \frac{14}{13} - 5 \frac{10}{13} = \frac{100}{13}.$
5. $(3 + \frac{4}{7}) - 2 = \frac{11}{7}.$
