Question

(-4 1/18-1 1/12+5 1/6):0,5+0,5

Answer 1

$(-4 \frac{1}{18} -1 \frac{1}{12} +5 \frac{1}{6} ):0.5+0.5 = \frac{7}{9} \\ 1) -4 \frac{1}{18} -1 \frac{1}{12} +5 \frac{1}{6} =-4 \frac{2}{36} -1 \frac{3}{36} +5 \frac{6}{36} = \frac{5}{36} \\ 2) \frac{5}{36} : \frac{1}{2} = \frac{5*2}{36} = \frac{5}{18} \\ 3) \frac{5}{18} + \frac{1}{2} = \frac{5}{18} + \frac{9}{18} = \frac{14}{18} = \frac{7}{9}$

Answer 2

Давайте решим это математическое выражение шаг за шагом:

\[ \begin{align*} & (-4 + \frac{1}{18} - 1 + \frac{1}{12} + 5 + \frac{1}{6}) \div (0.5 + 0.5) \\ = & (-4 + \frac{1}{18} - 1 + \frac{1}{12} + 5 + \frac{1}{6}) \div 1 \\ = & -4 + \frac{1}{18} - 1 + \frac{1}{12} + 5 + \frac{1}{6} \\ = & -4 - \frac{18}{18} - \frac{12}{12} + \frac{1}{18} + \frac{1}{12} + \frac{30}{18} \\ = & -4 - 1 - 1 + \frac{1}{18} + \frac{1}{12} + \frac{30}{18} \\ = & -6 + \frac{1}{18} + \frac{1}{12} + \frac{30}{18} \\ = & -6 + \frac{1 + 3 + 30}{18} \\ = & -6 + \frac{34}{18} \\ = & -6 + \frac{17}{9} \\ = & -\frac{54}{9} + \frac{17}{9} \\ = & -\frac{37}{9}. \end{align*} \]

Итак, результат выражения \((-4 + \frac{1}{18} - 1 + \frac{1}{12} + 5 + \frac{1}{6}) \div (0.5 + 0.5)\) равен \(-\frac{37}{9}\).
