Question

(b-a-5/6) + (0,5-a-b) = ?

Answer 1

Решение:

$(b - a - \frac{5}{6} ) + (0,5 - a - b) = b - a - \frac{5}{6} + 0,5 - a - b =(b - b) + ( - a - a ) + ( - \frac{5}{6} + 0.5) = 0 + ( - 2a) + ( - \frac{5}{6} + \frac{1}{2} ) = - 2a + ( - \frac{5}{6} + \frac{3}{6} ) = - 2a + ( - ( \frac{5}{6} - \frac{3}{6} )) = - 2a + ( - \frac{2}{6}) = - 2a + ( - \frac{1}{3} ) = - 2a - \frac{1}{3}.$

Ответ:

$- 2a - \frac{1}{3}.$
