Помогите решить) Очень надо!

Answer 1

$5 + \frac{1}{9} - 7 + \frac{1}{3} = - 2 + \frac{1 + 3}{9} = \\ = - 1 \frac{5}{9}$
$3 - 10 + \frac{1}{7} - \frac{2}{14} = - 7 + \frac{1}{7} - \frac{1}{7} = \\ = - 7$
$\frac{5}{8} - 4 - \frac{7}{24} + 9 = 5 + \frac{15 - 7}{24} = \\ = 5 + \frac{8}{24} = 5 \frac{1}{3}$
$- \frac{4}{15} - \frac{3}{5} - 1 + 8 = - \frac{4 + 9}{15} + 7 = \\ = - \frac{5}{15} + 7 = - \frac{1}{3} + 7 = 6 \frac{2}{3}$
