Answer 2

А)

$2 \frac{4}{7} - \frac{5}{7} = \frac{18}{7} - \frac{5}{7} = \frac{18 - 5}{7} = \frac{13}{7} = 1 \frac{6}{7}$

b)

$13\frac{2}{11} + 4 \frac{5}{22} = 13 + 4 + \frac{2}{11} + \frac{5}{22} = 17 + \frac{4}{22} + \frac{5}{22} = 17 + \frac{4 + 5}{22} = 17 \frac{9}{22}$

c)

$6 - \frac{2}{7} = 5 + \frac{7}{7} - \frac{2}{7} = 5 + \frac{7 - 2}{7} = 5 \frac{5}{7}$

d).

$\frac{3}{39} + \frac{2}{13} = \frac{3}{39} + \frac{6}{39} = \frac{9}{39} = \frac{3}{13}$
