解答

展开

\frac{3 ( 6 + 11 M )}{44}

\frac{9}{22} + \frac{3 M}{4}

求解步骤

\frac{3 ( 6 + 11 M )}{44}

乘开

3 (6 + 11 M) : 18 + 33 M

= \frac{18 + 33 M}{44}

使用分式法则:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{18 + 33 M}{44} = \frac{18}{44} + \frac{33 M}{44}

= \frac{18}{44} + \frac{33 M}{44}

消掉

\frac{18}{44} : \frac{9}{22}

= \frac{9}{22} + \frac{33 M}{44}

消掉

\frac{33 M}{44} : \frac{3 M}{4}

= \frac{9}{22} + \frac{3 M}{4}
