化簡:$\frac{41}{3}-[\frac{17}{4}-( \frac{51}{4}\times\frac{21}{2})]$.
已知: $\frac{41}{3}-[\frac{17}{4}-( \frac{51}{4}\times\frac{21}{2})]$.
要求:化簡:$\frac{41}{3}-[\frac{17}{4}-( \frac{51}{4}\times\frac{21}{2})]$.
解答
$\frac{41}{3}-[\frac{17}{4}-( \frac{51}{4}\times\frac{21}{2})]$
$=\frac{41}{3}-[\frac{17}{4}-( \frac{1071}{8})]$
$=\frac{41}{3}-[\frac{34-1071}{8}]$
$=\frac{41}{3}-[\frac{-1037}{8}]$
$=\frac{41}{3}+\frac{1037}{8}$
$=\frac{328+3111}{24}$
$=\frac{3439}{24}$
