题目：我们知道‘甲数除以乙数等于甲数乘以乙数的倒数‘.如果记甲数为\frac{b}{a}，乙数为\frac{d}{c}，那么该法则可以用符号表示为( ) 
选项：
bullet: A
text: \frac{b}{a}+\frac{d}{c}=\frac{b+d}{a+c}
bullet: B
text: \frac{b}{a}×\frac{d}{c}=\frac{b×d}{a×c}
bullet: C
text: \frac{b}{a}÷\frac{d}{c}=\frac{b÷d}{a÷c}
bullet: D
text: \frac{b}{a}÷\frac{d}{c}=\frac{b}{a}×\frac{c}{d}
答案：D
解析：\frac{d}{c}的倒数是\frac{c}{d};\frac{b}{a}÷\frac{d}{c}=\frac{b}{a}×\frac{c}{d}; 故选:D.
