2.上海七年级分式练习题篇二

【反思】本题是义务教育教科书苏科版《数学》八年级下册第112页第4 (1) 题, 它是一道典型的分式化简求值题. 这类问题是常见的代数式求值题, 往往先对分式化简, 再将字母代入其中或选择一个能够使代数式有意义的字母值代入其中进行运算求得结果, 有时也与不等式、方程联立设计成隐含条件求得分式的值. 分式求值题往往得到中考命题者的青睐, 现以近年来的中考题为例加以说明.

一、先化简, 再求值

例1 (2015·安徽) 先化简, 再求值:, 其中.

【解析】先应用分式的运算法则、基本性质对分式进行化简, 再将字母代入其中计算求值.

【策略】分式的求值题, 往往先化简再代入求值比较简捷, 直接代入其中较为繁琐且易错.

二、一次方程与分式求值题

例2 (2015·资阳) 先化简, 再求值:, 其中x满足2x-6=0.

【解析】根据分式运算的法则先把分式化简成最简分式, 然后再求得未知数的值代入计算.

【策略】解答这类以一元一次方程的解为条件的分式的混合运算求值题, 其关键是牢固掌握分式运算的法则与步骤, 先化简分式, 再求得一元一次方程的解, 最后代入其中求结果.

例3 (2015·通辽) 先化简, 再求值:, 其中a, b满足|a-3|+ (b-2) 2=0.

【解析】本题考查了分式的化简求值, 解题的关键是熟练掌握分式混合运算和利用非负数的性质列方程组求未知数的值.

∵|a-3|+ (b-2) 2=0,

∴a-3=0, b-2=0, 即a=3, b=2,

当a=3, b=2时, .

【策略】解答这类问题时, 往往先应用非负数的性质建立方程组, 求得方程组的解, 最后代入化简后的分式中计算求得结果.

三、应用参数求分式的值

例4 (2015·东营) 若, 则的值为 ( ) .

【解析】由, 可设x=4k, y=3k, 则.因此, 本题应该选D.

【策略】涉及两个字母的比值条件时, 往往应用参数代入其中计算比较简便.

四、整体代入求分式的值

例5 (2015·河北) 若a=2b≠0, 则的值为_______.

【解析】先对所求分式进行约分化简, 得:, 再将a=2b代入其中可得:, 因此, 本题应该填:.

【策略】这类问题, 往往先化简, 再用含有一个字母的代数式作为整体代入其中进行计算求得结果.

例6 (2014·菏泽) 已知x2-4x+1=0, 求的值.

【解析】若是把方程x2-4x+1=0 的根代入化简后的代数式中, 计算过程会比较复杂, 而且目前也不能求得方程的解.因此, 先将分式通分, 化为同分母分式后进行计算, 再将已知条件适当变形为x2-4x=-1, 而后把x2-4x看成整体代入求值.

【策略】本题没有直接求出字母x的值, 而是把x2-4x看成是一个整体, 巧妙地求得结果.本题渗透了整体代入的数学思想.

四、开放性条件求分式的值

例7 (2015·黔西南) 先化简:, 再代入一个合适的x求值.

【解析】先化简分式, 再选择使分式有意义的x的值代入其中进行计算.

因为x+1≠0且x≠0,

所以x≠-1且x≠0,

所以, 当x=2时, .

【策略】这是一道自主性较强的分式化简求值题, 能够较好地体现个性的差异性, 选择的字母值一定要能够使原代数式有意义. 特别要注意的是作为除式的分子不能为0哦!

例8 (2015·淮安) 先化简, 再从1, 2, 3三个数中选择一个合适的数作为x的值, 代入求值.

【解析】先化简分式, 再从所给的字母值中选择使分式有意义的字母x的值代入其中进行计算.

因为x-1≠0且x-2≠0,

所以x≠1且x≠2,

当x=3时, 原式=3-2=1.

【策略】这类分式的化简求值题, 选取喜欢的值代入时, 注意要使所有分式及整个计算过程都有意义, 不要落入“陷阱”中.

五、说理论证与求分式的值

例9 (2015·广元) 先化简:, 然后解答下列问题:

(1) 当x=3时, 求代数式的值;

(2) 原代数式的值能等于-1吗? 为什么?

【考点解剖】本题考查了分式的化简求值. 解题的关键是利用分解因式的方法化简分式. 此时要注意把各分子、分母先因式分解, 约分后再做减法运算;还要注意先把除法运算转化为乘法运算, 然后约分化为最简形式.

【解析】 (1) 这是个分式除法与减法混合运算题, 运算顺序是先计算括号内的, 再进行除法运算, 并将x=3代入计算即可; (2) 根据条件建立方程求得x=0, 此时除式, 原式无意义, 从而得出原代数式的值不能等于-1.

(1) 当x=3时, 原式=2;

(2) 如果, 那么x+1=-x+1,

∴x=0.

当x=0时, 无意义,

∴原代数式的值不能等于-1.

5.初中分式方程练习题篇五

中考数学方程应用题是近几年来中考的必考题，需要敏一定的阅读理解能力、分析解决问题的能力和计算能力，合理利用已知条件，构建方程，从而解决问题。

一单一的方程应用题

例1、(湖北十堰8分)一辆汽车开往距离出发地180千米的目的地，按原计划的速度匀速行驶60千米后，再以原来速度的1.5倍匀速行驶，结果比原计划提前40分钟到达目的地，求原计划的行驶速度.

解：设原计划的行驶速度为x千米/时，则：

，解得x=60，

经检验：x=60是原方程的解，且符合题意。所以x=60。

答：原计划的行驶速度为60千米/时。

二方程不等式应用题

例2、(2012湖北十堰10分)某工厂计划生产A、B两种产品共50件，需购买甲、乙两种材料.生产一件A产品需甲种材料30千克、乙种材料10千克;生产一件B产品需甲、乙两种材料各20千克.经测算，购买甲、乙两种材料各1千克共需资金40元，购买甲种材料2千克和乙种材料3千克共需资金105元.

(1)甲、乙两种材料每千克分别是多少元?

(2)现工厂用于购买甲、乙两种材料的资金不超过38000元，且生产B产品不少于28件，问符合条件的生产方案有哪几种?

(3)在(2)的条件下，若生产一件A产品需加工费200元，生产一件B产品需加工费300元，应选择哪种生产方案，使生产这50件产品的成本最低?(成本=材料费+加工费)

解：(1)设甲材料每千克x元，乙材料每千克y元，则

，解得。

答：甲材料每千克15元，乙材料每千克25元;

(2)设生产A产品m件，生产B产品(50-m)件，则生产这50件产品的材料费为

15×30m+25×10m+15×20×(50-m)+25×20×(50-m)=-100m+40000，

由题意：，解得20≤m≤22。

又∵m是整数，∴m的值为20， 21，22。∴共有三种方案，如下表：

装厂有A、B 两个制衣车间，A 车间每天加工的数量是B车间的1.2 倍，A、B 两车间共同 3.2012湖北黄冈)某服装厂设计了一款新式夏装，想尽快制作8800 件投入市场，服

完成一半后，A 车间出现故障停产，剩下全部由B 车间单独完成，结果前后共用20 天完成，

求A、B 两车间每天分别能加工多少件.

解：设B车间每天能加工x件，则A车间每天能加工1.2x件，由题意得：

，解得：x=320。

经检验：x=320是原分式方程的解。1.2×320=384。

答：A车间每天能加工384件，B车间每天能加工320件。

4.(北京市)列方程或方程组解应用题：某园林队计划由6名工人对180平方米

的区域进行绿化，由于施工时增加了2名工人，结果比计划提前3小时完成任务。若每人每

小时绿化面积相同，求每人每小时的绿化面积。

解：设每人每小时的绿化面积x平方米，由题意，得

，解得：x=2.5.

经检验，x=2.5是原方程的解，且符合题意.

答：每人每小时的绿化面积2.5平方米

5、(20重庆市)随着铁路运量的不断增长，重庆火车北站越来越拥挤，为了满足铁路交通的快速发展，该火车站从去年开始启动了扩建工程，其中某项工程，甲队单独完成所需时间比乙队单独完成所需时间多5个月，并且两队单独完成所需时间的乘积恰好等于两队单独完成所需时间之和的6倍。

(1)求甲、乙队单独完成这项工程各需几个月?

(2)若甲队每月的施工费为100万元，乙队每月的施工费比甲队多50万元，在保证工程质量的前提下，为了缩短工期，拟安排甲、乙两队分工合作完成这项工程。在完成这项工程中，甲队施工时间是乙队施工时间的2倍，那么，甲队最多施工几个月才能使工程款不超过1500万元?(甲、乙两队的施工时间按月取整数)

解：(1)设甲队单独完成这项工程需要个月，则乙队单独完成这项工程需要个月，

由题意得：整理得

解得，,不符合题意，应舍去，故，

答：甲队单独完成这项工程需要15个月，乙队单独完成这项工程需要10个月。

(2)设在完成这项工程中，甲队做了个月，则乙队做了个月，根据题意得：

分式方程应用题(列式部分省略)

1、A、B两地的距离是80公里，一辆公共汽车从A地驶出3小时后，一辆小汽车也从A地出发，它的速度是公共汽车的3倍，已知小汽车比公共汽车迟20分钟到达B地，求两车的速度。

【提示】设共交车速度为x，小汽车速度为3x，列方程得：80/(3x) +3=80/x +20/60

2、为加快西部大开发，某自治区决定新修一条公路，甲、乙两工程队承包此项工程。如果甲工程队单独施工，则刚好如期完成;如果乙工程队单独施工就要超过6个月才能完成，现在甲、乙两队先共同施工4个月，剩下的由乙队单独施工，则刚好如期完成。问原来规定修好这条公路需多长时间?

【提示】设时间为x个月，列方程得：[1/x+1/(x+6)]*4+(x-4)/(x+6)=1

3、某工人原计划在规定时间内恰好加工1500个零件，改进了工具和操作方法后，工作效率提高为原来的2倍，因此加工1500个零件时，比原计划提前了五小时，问原计划每小时加工多少个零件?

【提示】设原计划每小时加工x个零件，列方程得：1500/2x +5=1500/x

4、甲、乙两组学生去距学校4.5千米的敬老院打扫卫生，甲组学生步行出发半小时后，乙组学生骑自行车开始出发，结果两组学生同时到达敬老院，如果步行的速度是骑自行车的速度的1/3，求步行和骑自行车的速度各是多少?

【提示】设步行的速度是每小时x千米，则4.5/3x +0.5=4.5/x

5、某质检部门抽取甲、乙两个相同数量的产品进行质量检测，结果甲厂有48件合格产品，乙厂有45件合格产品，甲厂合格率比乙厂高5%，求抽取检验的产品数量及甲厂的合格率。

【提示】设抽取检验的产品数量为x，则(48/x -45/x)*100%=5%

6、某车间加工1200个零件后，采用了新工艺，工效提高50%，这样加工同样多的零件就少用10小时，采用新工艺前后每小时分别加工多少个零件?

7、A、B两地相距48千米，一艘轮船从A地顺流航行至B地，又立即从B地逆流返回A地，共用去9小时，已知水流速度为4千米/时，若设该轮船在静水中的速度为x千米/时，则可列方程求解。

【提示】48/(x+4) +48/(x-4)=9

Last week Fred had to go to New York. It was his first time there, and he didn’t know his way around the city. He had a meeting at 10 o’clock, and he wanted to be there on time. The meeting was in the Pe-terson Building on 34th Street, but Fred didn’t know where that was. Seeing two men standing on a corner, he asked them.

“Excuse me,” he said, “but can you tell me how to get to the Pe-terson Building on 34th Street?”

“Sure,” answered one of them. “You can get there in five minutes. Go to the next corner and turn left. Walk three blocks and there you are.”

But the other man said, “There’s a better way. Go on the bus here at the corner. It stops right near the Peters Building.”

“Not Peters,” Fred told him, “Peterson.”

Then the first man said, “Oh, that’s on East 34th Street, not West 34th. It’s quite a distance（距离） from here. You will have to take the subway（地铁）.”

But the second man told Fred, “No, don’t go by subway. Take the crosstown(穿城而过) bus. It goes to the Peterkin Building.”

“Peterson, not Peterkin,” Fred looked at his watch. It was almost ten o’clock. “Thanks a lot.” Fred said, “I think I’ll take a taxi.”

When he got into the taxi he saw the two men arguing and pointing in different direction. Next time he wanted to know how to get to a place, he’d better ask a policeman!
