方程与不等式是现实世界中相等关系和不等关系的数学表示形式,它们不仅是现阶段学习的重点内容,而且也是同学们后继学习的基础.七年级阶段我们已学习一元一次方程、二元一次方程组、一元一次不等式(组),在期末复习过程中又有哪些难点需要注意呢?不妨一起来梳理一下.一、分母中含有小数的方程利用分数的性质,使分数的分子和分母同时扩大相同的倍数,将小数化为整数. Equations and inequalities are mathematical representations of equal and unequal relations in the real world, and they are not only the focus of current study, but also the basis for students’ subsequent learning. In the seventh grade, we have studied the equations of the first order, Equations, unary inequality (group), what are the difficulties in the review process at the end of the period you need to pay attention? May be combed together. First, the denominator contains the decimal fraction of the nature of the use of fractions, the fractional numerator and denominator while expanding The same multiple, the decimal integer.
