第八周 转化单位“1”(三)专题简析:解答较复杂的分数应用题时,我们往往从题目中找出不变的量,把不变的量看作单位“1”,将已知条件进行转化,找出所求数量相当于单位“1”的几分之几,再列式解答。
例题1。
有两筐梨。
乙筐是甲筐的35 ,从甲筐取出5千克梨放入乙筐后,乙筐的梨是甲筐的79 。
甲、乙两筐梨共重多少千克?解: 5÷(55+3 -97+9)=80(千克)答:甲、乙两筐梨共重80千克。
练习11. 某小学低年级原有少先队员是非少先队员的13,后来又有39名同学加入少先队组织。
这样,少先队员的人数是非少先队员的78。
低年级有学生多少人?2. 王师傅生产一批零件,不合格产品是合格产品的119 ,后来从合格产品中又发现了2个不合格产品,这时算出产品的合格率是94%。
合格产品共有多少个?3. 某校六年级上学期男生占总人数的54%,本学期转进3名女生,转走3名男生,这时女生占总人数的48%。
现在有男生多少人?例题2。
某学校原有长跳绳的根数占长、短跳绳总数的38 。
后来又买进20根长跳绳,这时长跳绳的根数占长、短跳绳总数的712 。
这个学校现有长、短跳绳的总数是多少根?解法一:根据短跳绳的根数没有变,我们把短跳绳看作单位“1”。
可以得出原来的长跳绳根数占短跳绳根数的38-3 ,后来长跳绳是短跳绳的712-7。
这样就找到了20根长跳绳相当于短跳绳的(712-7 -38-3 ),从而求出短跳绳的根数。
再用短跳绳的根数除以(1-712)就可以求出这个学校现有跳绳的总数。
即20÷(712-7 -38-3 )÷(1-712 )=60(根)解法二:把短跳绳看作单位“1”,原来的总数是短跳绳的88-3,后来的总数是短跳绳的1212-7。
所以20÷(1212-7 -88-3 )÷(1-712 )=60(根)答:这个学校现有长、短跳绳的总数是60根。
练习21. 阅览室看书的同学中,女同学占35,从阅览室走出5位女同学后,看书的同学中,女同学占47,原来阅览室一共有多少名同学在看书?2. 一堆什锦糖,其中奶糖占45%,再放入16千克其他糖后,奶糖只占25%,这堆糖中有奶糖多少千克? 3. 数学课外兴趣小组,上学期男生占59 ,这学期增加21名女生后,男生就只占25了,这个小组现有女生多少人?例题3。
