专题三 与有理数的乘除有关的应用问题
5. 张在办理业务时，约定存入为正，取出为负．2012年6月29日他办理了6件业务：-780元、-650元、+1250元、-310元、-420元、+240元．
（1）若他早上领取备用金5000元，那么下班时应交回银行多少元？

状元笔记
【知识要点】
1. 两数相乘，同号得正，异号得负，并把绝对值相乘；任何数同0相乘，都得0．
2. 乘积是1的两个数互为倒数．
3. (1)几个不等于0的数相乘，积的符号由负因数的个数决定．当负因数有奇数个时，积为负；当负因数有偶数个时，积为正．
(2)几个数相乘，有一个因数为0，积就为0．
【方法技巧】
1. 有理数乘法运算的方法与步骤：
第一步确定符号；
第二步计算积的绝对值；
第三步写出结果.
对于有理数的除法运算,应先将除法转化为乘法,再按乘法运算的方法和步骤进行运算.
2.（1）同级运算按从左到右的顺序进行；
（2）要注意算式中有没有括号，如有括号，要按小括号——中括号──大括号的顺序
进行；
（3）灵活运用运算律简化运算.

参考答案
1．C 解析：因为 79=63，所以两手伸出的手指数和为6，未伸出手指数的积为3，满足以上两个条件左、右手依次伸出手指的个数必须是2，4.故选C.
2. 解析：观察题目中图形的规律发现：每个图形中小正方形的个数等于与之对应的式序数，且每个图形被等分的份数等于左边等式中分式的分母，其阴影部分份数等于相应的分式的分子，由此可得（1）问的图形.且由上面探索可以很方便地得到本题的等式规律，即第（2）问的答案.
解：

(2) .
3. 解：原式=（100﹣）×（﹣6）=100×（﹣6）﹣×（﹣6）=﹣600+=-599．
4. 解：（1）解法一是错误的，解法二、三是正确的，解法三较简捷.

.
5. 解：（1）5000-780-650+1250-310-420+240=4330（元）；他下班时应交回银行4330元.
（2）（780+650+1250+310+420+240）×0.1%=3.65（元），这天他应得奖金为3.65元．
6. 解：（1）20+4+5-1=28（元）．答：到本周三，小张所持股票每股28元．
（2）20+4+5=29（元）．答：本周内，股票最高价出现在星期二，是29元．
（3）29-1-3-6=19（元），1000×19=19000（元），1000×20=20000（元），
19000-20000-20000×1.5‰-19000×（1.5‰+3‰）=-1000-30-85.5=-1115.5（元）．
所以小张亏了1115.5元．
