化简 a/b+b/a+b/c+c/b+a/c+c/a+3

解答

化简

\frac{a}{b} + \frac{b}{a} + \frac{b}{c} + \frac{c}{b} + \frac{a}{c} + \frac{c}{a} + 3

\frac{a + c}{b} + \frac{b + c}{a} + \frac{b + a}{c} + 3

求解步骤

\frac{a}{b} + \frac{b}{a} + \frac{b}{c} + \frac{c}{b} + \frac{a}{c} + \frac{c}{a} + 3

化简

\frac{a}{b} + \frac{c}{b} : \frac{a + c}{b}

= \frac{a + c}{b} + \frac{b}{a} + \frac{b}{c} + \frac{a}{c} + \frac{c}{a} + 3

化简

\frac{b}{a} + \frac{c}{a} : \frac{b + c}{a}

= \frac{a + c}{b} + \frac{b + c}{a} + \frac{b}{c} + \frac{a}{c} + 3

化简

\frac{b}{c} + \frac{a}{c} : \frac{b + a}{c}

= \frac{a + c}{b} + \frac{b + c}{a} + \frac{b + a}{c} + 3
