Question

Efectuati calculele: -1 intreg si 1/6-(2 intregi si 1/8+7/2)-1,0(6).

Answer 1

$- 1 \frac{1}{6} - (2 \frac{1}{8} + \frac{7}{2} ) - 1.0(6) = \\ \\ = - \frac{7}{6} - ( \frac{17}{8} + \frac{7}{2} ) - 1 \frac{6}{9} = \\ \\ = - \frac{7}{6} - ( \frac{17 + 28}{8} ) - \frac{15}{9} = \\ \\ = - \frac{7}{6} - \frac{45}{8} - \frac{5}{3} = \\ \\ = - \frac{28 + 135 + 40}{24 } = \\ \\ = - \frac{203}{24}$
