分式的基本性质是:分式的分子和分母都乘(或除以)同一个不等于0的整式,分式的值不变,用式子表示为:B÷A=(B×M)÷(A×M),A÷B=(A÷M)÷(B÷M)(M≠0),其中A、B、M均为整式,它是分式化简、变形、分式加减法和乘除法运算的重要依据,也是同学们学习的一个十分重要的内容,现将运用它解题的几种形式归纳如下,供同学们学习时参考. The basic nature of fractions is that the fractional numerator and denominator are multiplied (or divided by) by the same integer not equal to 0, and the fractional value remains unchanged, expressed as: B ÷ A = (B × M) ÷ (A × M), A ÷ B = (A ÷ M) ÷ (B ÷ M) (M ≠ 0), where A, B and M are all integers. An important basis for subtraction and multiplication and division operations, but also a very important content for students to learn, now use it to solve several forms of induction are summarized as follows for students to learn reference.
