同学们知道,在我们现实生活中,存在着许许多多与数学知识紧密联系的问题,而以前只是限于知识的匮乏,一直无法求解,随着数学知识的进一步丰富,许多的问题已经能够解决了,为了方便同学们的复习,现在就能运用八年级的数学知识求解的问题举例说明.一、利用分式运算知识求解例1甲、乙两位采购员同去一家饲料公司购买两次饲料,两次饲料的价格有变化,两位采购员的购货方式也不同,其中,甲每次购买1000千克,乙每次用去800 Students know that in our real life, there are many problems that are closely linked with mathematical knowledge. Previously, the problem was limited to the lack of knowledge and never solved. With the further enrichment of mathematics, many problems have been solved , In order to facilitate the students' review, now you can use the eighth grade mathematics to solve the problem as an example.First, the use of fractional operation knowledge to solve Example 1 A, B two buyers with a feed company to buy two feed, Twice the price of feed has changed, the purchase of two buyers are also different ways, of which, each purchase of 1000 kg, B each spent 800
