求解步骤

- 5 \div \frac{2}{3}

将项转换为分式:

5 = \frac{5}{1}

= - \frac{5}{1} \div \frac{2}{3}

使用分式法则:

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

= - \frac{5}{1} \times \frac{3}{2}

使用法则

\frac{a}{1} = a

= - 5 \times \frac{3}{2}

5 = \frac{5}{1}

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

分式相乘:

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

= - \frac{5 \times 3}{1 \times 2}
