-(19 4/15 - 21,095) + (8 1/5 - 18,975) - (-11 2/3 + 2,12)

Решите задачу:

$- (19 \frac{4}{15} - 21.095 )+ (8 \frac{1}{5} - 18.975) - ( - 11 \frac{2}{3} + 2.12) = - 19 \frac{4}{15} + 21.095+8 \frac{1}{5} - 18.975 + 11 \frac{2}{3} - 2.12 = \frac{3}{5} + 0 = \frac{3}{5} = 0.6\\ 1) \: \: \: - 19 \frac{4}{15} + 8 \frac{3}{15} + 11 \frac{10}{15} = \frac{ - 4 + 3 + 10}{15} = \frac{9}{15} = \frac{3}{5} \\ 2) \: \: \: 21.095 - 18.975 - 2.12 = 2.12 - 2.12 = 0$
