(11)/x =(2.5)/(5.5)

解答

\frac{11}{x} = \frac{2.5}{5.5}

解答

x = 24.2

求解步骤

\frac{11}{x} = \frac{2.5}{5.5}

使用分式交叉相乘

60.5 = x \cdot 2.5

交换两边

x \cdot 2.5 = 60.5

两边除以

2.5

x = 24.2

验证解

找到无定义的点（奇点）:

x = 0

将不在定义域的点与解相综合:

x = 24.2

流行的例子

\frac{3}{x} = \frac{4}{8}

((x/(x^2))^3)^2=x

((\frac{x}{x ^{2}})^{3})^{2} = x

4.039 = \frac{2 π}{t}

(x^2+2x)/(x+2)=2

\frac{x ^{2} + 2 x}{x + 2} = 2

(sqrt(3))/2 = 6/x

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