Answer 1

SOLUCIÓN

$\frac{2}{1} + \frac{3}{8} - (5 - 6 + \frac{7}{12} ) + \frac{1}{3} \times \frac{1}{8}$

Desarrollo de la expresión

$= \frac{2 \times 8 + 3}{8} -( - 1 + \frac{7}{12} ) + \frac{1}{24}$

$= \frac{16 + 3}{8} - ( \frac{ - 12 + 7}{12} ) + \frac{1}{24}$

$= \frac{19}{8} - ( \frac{ - 5}{12} ) + \frac{1}{24}$

$= \frac{19}{8} + \frac{5}{12} + \frac{1}{24}$

$= \frac{19 \times 12 \times 24 + 5 \times 8 \times 24 + 1 \times 8 \times 12}{8 \times 12 \times 24}$

$= \frac{5472 + 960 + 96}{2304}$

$= \frac{6528}{2304}$

$= \frac{17}{6}$
