Question

(5/6+2/3-1/4)+(7-1/2-1/3)=

Answer 1

$( \frac{5}{6} + \frac{2}{3} - \frac{1}{4} ) + (7 - \frac{1}{2} - \frac{1}{3} ) =$

$( \frac{10}{12} + \frac{8}{12} - \frac{3}{12} ) + ( \frac{42}{6} - \frac{3}{6} - \frac{2}{6} ) =$

$\frac{10 + 8 - 3}{12} + \frac{42 - 3 - 2}{6} =$

$\frac{15}{12} + \frac{37}{6} =$

$\frac{15}{12} + \frac{74}{12} =$

$= \frac{89}{12}$
