Answer 2

a)

$\frac{4}{5} - \frac{1}{7} \ \\ \\ \ \frac{28}{35} - \frac{5}{35} \ \\ \\ \frac{28 - 5}{35} \\ \\ \frac{23}{35}$

b)

$\frac{5}{6} - \frac{1}{4} + \frac{2}{9} \\ \\ \frac{30}{36} - \frac{9}{36} + \frac{8}{36} \\ \\ \frac{30 - 9 + 8}{36} \\ \\ \frac{29}{36}$

c)

$\frac{7}{18} - \frac{1}{24} \\ \\ \frac{28}{72} - \frac{3}{72} \\ \\ \frac{28 - 3}{72} \\ \\ \frac{25}{72}$
