求解步骤

3 \div 4 \div 3 \div 2

遵循 PEMDAS 运算顺序

乘除（左右）

3 \div 4 = \frac{3}{4}

= \frac{3}{4} \div 3 \div 2

\frac{3}{4} \div 3 = \frac{1}{4}

\frac{3}{4} \div 3

将项转换为分式:

3 = \frac{3}{1}

= \frac{3}{4} \div \frac{3}{1}

使用分式法则:

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

= \frac{3}{4} \cdot \frac{1}{3}

交叉约分:

3

= \frac{1}{4}

= \frac{1}{4} \div 2

\frac{1}{4} \div 2 = \frac{1}{8}

\frac{1}{4} \div 2

将项转换为分式:

2 = \frac{2}{1}

= \frac{1}{4} \div \frac{2}{1}

使用分式法则:

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

= \frac{1}{4} \cdot \frac{1}{2}

分式相乘:

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

= \frac{1 \cdot 1}{4 \cdot 2}

数字相乘:

1 \cdot 1 = 1

= \frac{1}{4 \cdot 2}

数字相乘:

4 \cdot 2 = 8

= \frac{1}{8}

= \frac{1}{8}
