化简

\frac{5}{6} + \frac{2}{4} + \frac{7}{11}

\frac{65}{33}

十进制

1.96969 \dots

求解步骤

\frac{5}{6} + \frac{2}{4} + \frac{7}{11}

消掉

\frac{2}{4} : \frac{1}{2}

= \frac{5}{6} + \frac{1}{2} + \frac{7}{11}

\frac{5}{6} + \frac{1}{2} + \frac{7}{11} = \frac{130}{66}

= \frac{130}{66}

消掉

\frac{130}{66} : \frac{65}{33}

= \frac{65}{33}
