求解步骤

6 \div 4 \div 5

遵循 PEMDAS 运算顺序

乘除（左右）

6 \div 4 = \frac{6}{4}

= \frac{6}{4} \div 5

\frac{6}{4} \div 5 = \frac{3}{10}

\frac{6}{4} \div 5

将项转换为分式:

5 = \frac{5}{1}

= \frac{6}{4} \div \frac{5}{1}

使用分式法则:

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

= \frac{6}{4} \cdot \frac{1}{5}

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

\frac{6}{4}

约分:

2

= \frac{3}{2}

= \frac{3}{2} \cdot \frac{1}{5}

分式相乘:

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

= \frac{3 \cdot 1}{2 \cdot 5}

数字相乘:

3 \cdot 1 = 3

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

数字相乘:

2 \cdot 5 = 10

= \frac{3}{10}

= \frac{3}{10}
