$1\frac{1}{3} -2\frac{1}{2} +\frac{7}{8} - \frac{1}{2}$

Answer 1

Respuesta:

$1 \frac{1}{3} - 2 \frac{1}{2} + \frac{7}{8} - \frac{1}{2} = \\ \\ ( \frac{3 \times 1 + 1}{3} ) - ( \frac{2 \times 2 + 1}{2} ) + \frac{7}{8} - \frac{1}{2} = \\ \\ \frac{4}{3} - \frac{5}{2} + \frac{7}{8} - \frac{1}{2} = \\ \\ \frac{32 - 60 + 21 - 12}{24} = - \frac{19}{24}$
