Задание 695. (5 тоже)

Решите задачу:

$5 + 7 \frac{3}{8} + 3 \frac{1}{8} = 5 + 7 + 3 + \frac{3}{8} + \frac{1}{8} = 15 \frac{4}{8} = 15.5$

$4 \frac{2}{5} + 6 + 1 \frac{1}{5} = 4 + 6 + \frac{2}{5} + \frac{1}{5} = 10 \frac{3}{5} = 10.6$

$1 \frac{5}{12} + 2 \frac{3}{12} + 3 \frac{2}{3} = 1 \frac{5}{12} + 2 \frac{3}{12} + 3 \frac{8}{12} = 6 + ( \frac{5 + 3 + 8}{12} ) = 6 \frac{16}{12} = 7 \frac{4}{12} = 7 \frac{1}{3}$

$4 \frac{2}{15} + \frac{7}{15} + 6 = (4 + 6) + ( \frac{2 + 7}{15}) = 10 \frac{9}{15} = 10 \frac{3}{5} = 10.6$

$6 \frac{5}{9} + 7 = 13 \frac{5}{9}$
