一、直接写出得数。
<Object: word/embeddings/oleObject1.bin>÷3= <Object: word/embeddings/oleObject2.bin>×2= <Object: word/embeddings/oleObject3.bin>÷3= 3÷<Object: word/embeddings/oleObject4.bin>=
<Object: word/embeddings/oleObject5.bin>×<Object: word/embeddings/oleObject6.bin>= <Object: word/embeddings/oleObject7.bin>－<Object: word/embeddings/oleObject8.bin>= 10×<Object: word/embeddings/oleObject9.bin>= <Object: word/embeddings/oleObject10.bin>+<Object: word/embeddings/oleObject11.bin>=
<Object: word/embeddings/oleObject12.bin>÷<Object: word/embeddings/oleObject13.bin>= <Object: word/embeddings/oleObject14.bin>÷<Object: word/embeddings/oleObject15.bin>= <Object: word/embeddings/oleObject16.bin>÷<Object: word/embeddings/oleObject17.bin>= <Object: word/embeddings/oleObject18.bin>÷<Object: word/embeddings/oleObject19.bin>=
二、填空。
1、40的<Object: word/embeddings/oleObject20.bin>是（ ）。 2、一个数的<Object: word/embeddings/oleObject21.bin>是25，这个数是（ ）。
3、45分=（ ）时 20分=（ ）时
60千克=（ ）吨 32分=（ ）元
4、<Object: word/embeddings/oleObject22.bin>=（ ）÷（ ）=（ ）︰（ ）=（ ）（填小数）
5、一批货物的<Object: word/embeddings/oleObject23.bin>是180吨，这批货物有（ ）吨。
6、已知a×<Object: word/embeddings/oleObject24.bin>=<Object: word/embeddings/oleObject25.bin>×b=c×<Object: word/embeddings/oleObject26.bin>,并且a、b、c都不等于0.那么，a、b、c按从小到大的顺序排列是（ ）。
7、有2吨货物，甲车每次运<Object: word/embeddings/oleObject27.bin>，乙车每次运<Object: word/embeddings/oleObject28.bin>吨。若单独运完这些货物，甲车需运（ ）次，乙车需运（ ）次。
三、计算下面各题。
<Object: word/embeddings/oleObject29.bin>÷[8×(<Object: word/embeddings/oleObject30.bin>－<Object: word/embeddings/oleObject31.bin>)] [1－(<Object: word/embeddings/oleObject32.bin>+<Object: word/embeddings/oleObject33.bin>)]÷<Object: word/embeddings/oleObject34.bin>
四、下面各题怎样算简便就怎样算。
（<Object: word/embeddings/oleObject35.bin>－<Object: word/embeddings/oleObject36.bin>）×<Object: word/embeddings/oleObject37.bin> （<Object: word/embeddings/oleObject38.bin>+<Object: word/embeddings/oleObject39.bin>）÷<Object: word/embeddings/oleObject40.bin> <Object: word/embeddings/oleObject41.bin>×<Object: word/embeddings/oleObject42.bin>－<Object: word/embeddings/oleObject43.bin>÷11
五、选择。（把正确答案的序号填在括号里）
1、电扇厂原计划生产电扇100万台，现在生产了120万台，增产了几分之几？
列式是（ ）。
A．120÷100－1 B.1－100÷12 C.(120－100) ÷120 D.(120－100) ÷100
2、一根绳子长4米，比另一根短<Object: word/embeddings/oleObject44.bin>米，另一根绳子长（ ）。
A．<Object: word/embeddings/oleObject45.bin>米 B．<Object: word/embeddings/oleObject46.bin>米 C．3米 D．<Object: word/embeddings/oleObject47.bin>米
六、解方程。
<Object: word/embeddings/oleObject48.bin>x－2=<Object: word/embeddings/oleObject49.bin> x÷<Object: word/embeddings/oleObject50.bin>=<Object: word/embeddings/oleObject51.bin> <Object: word/embeddings/oleObject52.bin>+<Object: word/embeddings/oleObject53.bin>x=<Object: word/embeddings/oleObject54.bin> <Object: word/embeddings/oleObject55.bin>x－<Object: word/embeddings/oleObject56.bin>x=10
七、解决实际问题。
1、一根电线杆全长的<Object: word/embeddings/oleObject57.bin>是2米，这根电线杆全长多少米？露出地面的部分占全长的<Object: word/embeddings/oleObject58.bin>，露出地面的部分是几米？
2、某乡去年绿色蔬菜的总产量比今年少<Object: word/embeddings/oleObject59.bin>，去年比今年少110吨，今年的产量是多少吨？
一个长方体，从同一顶点引出的3条棱共长24厘米，这个长方体的长、宽、高的比是
5︰4︰3，这个长方体的长、宽、高各是多少？
6、学校新购进了一些球，新购进的足球占购球总数的<Object: word/embeddings/oleObject60.bin>，新购进的足球有60个，学校新购进了多少个球？（用算术和方程两种方法解答）
★、甲、乙两汽车从A、B两地相向而行，相遇时所行路程比是5︰3，这时乙车距两地的中点还有80千米，求两地相距多少千米？
