化简 6 6/10 × 8/12

解答

化简

6 \frac{6}{10} \cdot \frac{8}{12}

4 \frac{2}{5}

十进制

4.4

求解步骤

6 \frac{6}{10} \cdot \frac{8}{12}

将带分数转换为假分式:

6 \frac{6}{10} = \frac{66}{10}

= \frac{66}{10} \cdot \frac{8}{12}

消掉

\frac{66}{10} : \frac{33}{5}

= \frac{33}{5} \cdot \frac{8}{12}

消掉

\frac{8}{12} : \frac{2}{3}

= \frac{33}{5} \cdot \frac{2}{3}

\frac{33}{5} \cdot \frac{2}{3} = \frac{22}{5}

= \frac{22}{5}

将假分式转换为带分数:

\frac{22}{5} = 4 \frac{2}{5}

= 4 \frac{2}{5}
