5 1/16-1 1/18*(5/6+3/14)

Решите задачу:

$5 \frac{1}{16} - 1 \frac{1}{18} \times ( \frac{5}{6} + \frac{3}{14} ) = 5 \frac{1}{16} - 1 \frac{1}{18} \times ( \frac{35}{42} + \frac{9}{42} ) = 5 \frac{1}{16} - \frac{19}{18} \times \frac{44}{42} = 5 \frac{1}{16} - 1 \frac{20}{189} = \frac{81}{16} - \frac{209}{189} = \frac{81 \times 189 - 209 \times 16}{3024} = \frac{11965}{3024} = 3 \frac{2893}{3024}$
