求解步骤

(4/6) (4/6)

遵循 PEMDAS 运算顺序

计算括号内的值

(4/6) : \frac{4}{6}

4/6

4/6 = \frac{4}{6}

= \frac{4}{6}

= \frac{4}{6} (4/6)

计算括号内的值

(4/6) : \frac{4}{6}

4/6

4/6 = \frac{4}{6}

= \frac{4}{6}

= \frac{4}{6} \cdot \frac{4}{6}

乘除（左右）

\frac{4}{6} \cdot \frac{4}{6} : \frac{4}{9}

\frac{4}{6} \cdot \frac{4}{6}

消掉

\frac{4}{6} : \frac{2}{3}

\frac{4}{6}

因式分解数字:

4 = 2 \cdot 2

= \frac{2 \cdot 2}{6}

因式分解数字:

6 = 2 \cdot 3

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

约分:

2

= \frac{2}{3}

= \frac{2}{3} \cdot \frac{4}{6}

消掉

\frac{4}{6} : \frac{2}{3}

\frac{4}{6}

因式分解数字:

4 = 2 \cdot 2

= \frac{2 \cdot 2}{6}

因式分解数字:

6 = 2 \cdot 3

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

约分:

2

= \frac{2}{3}

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

\frac{2}{3} \cdot \frac{2}{3} = \frac{4}{9}

\frac{2}{3} \cdot \frac{2}{3}

使用分式法则:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

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

数字相乘:

2 \cdot 2 = 4

= \frac{4}{3 \cdot 3}

数字相乘:

3 \cdot 3 = 9

= \frac{4}{9}

= \frac{4}{9}

= \frac{4}{9}
