32.8÷8＝9.3÷3＝5.6÷4＝6.5÷5＝20.5÷5＝
新课巩固：
已知条件：甲商店购买5袋牛奶一共11.5元，乙商店购买6袋牛奶一共12.6元，
要求问题：（1）甲商店的牛奶每袋多少元？（2）乙商店的牛奶每袋多少元？哪家商店的牛奶便宜？
（1）要求甲商店牛奶每袋多少元，就是用买牛奶的钱除以牛奶的数量，即“÷＝单价”，其中，11.5
是（），5是（），所以列式为。
（2）要求乙商店牛奶每袋多少元，就是用买牛奶的钱除以牛奶的数量，即“÷＝单价”，其中，12.6
是（），6是（），所以列式为。
（3）要知道哪个商店的牛奶便宜，只要把两个商店的牛奶的（）进行比较就可以了。
一、用竖式计算。
7.91÷7＝8.5÷5＝15.9÷3＝50.4÷6＝
19.5÷15＝28.9÷17＝57.6÷18＝18.2÷14＝
二、解决问题。
三、填一填。
1、佳佳买了8支中性笔，用去25.6元。
每支中性笔多少元？
2、彤彤家有5口人，上个月用水量是14.5吨，平均每人用水多少吨？
3、为了迎接2014世界园艺博览会，实验小学买了67.5中国结用红丝线多少米？ 0 这个4是() 24个()。
