参考答案与解析本部分从新页开始，按题号给出答案、关键过程、评分标准和易错点。选择题与填空题以结果为主，解答题按步骤给分。一、选择题答案题号12345678910答案BBCCBCCACB1.解析：7/12＋5/18－1/9＝21/36＋10/36－4/36＝27/36＝3/4，选B。易错点：通分时要统一到36，不能只把前两个分数通分后直接减1/9。2.解析：设这个数为x，75%x＝36，x＝36÷0.75＝48。48比60少12，12÷60＝20%，选B。易错点：“比60少百分之几”要以60为单位“1”，不能用12÷48。3.解析：末位能被5整除，只能是0或5。要使数最大，先尽量让百位大。百位为8、末位为5时，3＋8＋5＋5＝21，能被3整除，数为3855，选C。易错点：先比较千位、百位，再检查整除条件；不能只找一个能被3和5整除的数。4.解析：长＋宽＝64÷2＝32厘米。5＋3＝8份，每份32÷8＝4厘米，长20厘米，宽12厘米，面积20×12＝240平方厘米，选C。易错点：周长的一半才是长与宽的和，不是64直接按8份分。5.解析：总分为37×84＋3×90＝3108＋270＝3378分，全班40人，平均分3378÷40＝84.45分，选B。易错点：不能把84和90直接平均；两组人数不同，必须先求总分。6.解析：直径14厘米，半径7厘米，面积＝πr²＝22/7×7×7＝154平方厘米，选C。易错点：面积用半径，不用直径；直径14不能直接平方后乘π。7.解析：总份数3＋4＋5＝12份，每份96÷12＝8个，蓝球4份，4×8＝32个，选C。易错点：按比求量时先求一份量，不能把96直接乘4。8.解析：相遇点距甲地就是甲车2小时行驶的路程：42×2＝84千米，选A。易错点：题目问距甲地，不是两车速度和乘时间或乙车路程。9.解析：相邻两项差依次为3、5、7、9，下一个差为11，所以26＋11＝37，选C。易错点：观察差的变化，不要把后一项误看成前一项的2倍左右。10.解析：另两边和为18－7＝11。无序整数对有（1，10）（2，9）（3，8）（4，7）（5，6），满足两边之和大于第三边的有（3，8）（4，7）（5，6），共3组，选B。易错点：三角形必须任意两边之和大于第三边；等于第三边不能构成三角形。二、填空题答案题号111213141516答案12.52803.22840.824011.解析：2.4×1.25＋7.6×1.25＝（2.4＋7.6）×1.25＝10×1.25＝12.5。易错点：看到相同因数1.25可提取公因数，避免逐项小数乘法出错。12.解析：男生∶女生＝5∶7，总份数12份，每份480÷12＝40人，女生7份，7×40＝280人。易错点：480是男女总人数，不是女生人数；比中女生占7/12。13.解析：比例尺1∶50000表示图上1厘米代表实际50000厘米。6.4×50000＝320000厘米＝3.2千米。易错点：厘米换千米要除以100000，不能只除以1000。14.解析：两个数的乘积＝最大公因数×最小公倍数＝7×84＝588。另一个数＝588÷21＝28。易错点：本公式适用于两个正整数，不能把84÷7再乘21。15.解析：外圆半径6＋1＝7米，小路面积＝3.14×（7²－6²）＝3.14×13＝40.82平方米。易错点：环形面积是外圆面积减内圆面积，不是用路宽1米乘周长的近似值。16.解析：6个连续偶数平均数为35，说明中间两个偶数是34和36，这6个数为30、32、34、36、38、40，最大是40。易错点：偶数的平均数可以是奇数；6个数没有单独的中间数，要看中间两个数的平均。三、解答题答案、评分标准与易错点17.答案与解析（10分）（1）（5/6－3/8）÷7/12＋2/3＝（20/24－9/24）÷7/12＋2/3＝11/24×12/7＋2/3＝11/14＋2/3＝33/42＋28/42＝61/42＝1又19/42。（2）12.5×3.2×0.25＝12.5×（4×0.8）×0.25＝（4×0.25）×（12.5×0.8）＝1×10＝10。评分标准：每小题5分。第（1）小题正确通分1分，分数除法转乘法1分，异分母加法1分，结果化简1分，书写完整1分。第（2）小题合理拆数2分，利用结合律2分，结果1分。易错点：易错点：分数除法要乘倒数；小数简算中3.2可拆成4×0.8，不宜拆成3
