五年级数学第二单元自测题班级姓名等级一、认真思考,正确填空。1一个数的因数的个数是()的,其中最小的因数是(),最大的因数是();一个数的倍数的个数是(),其中最小的倍数是()2写出符合要求的最小三位数:既是的倍数又是的倍数();既是的倍数又是的倍数();既是和的倍数又是的倍数()。3.要使 1750 同是被 2、3、5 的倍数,最大能填()最小能填()。4.9的因数有()这些因数中,()既是奇数,又是合数,()既不是质数也不是合数。5一个四位数,千位上是最小的质数,百位上是最小的奇数,个位上是最小的合数,其余数位上的数字是0,这个数写作()。63007 至少要加上()就是 3 的倍数。7如果 a 的最大因数是19,b 的最小倍数是1,则 a+b 的和的所有因数有()a-b 的差的所有因数有()8有因数 3,也是 2 和 5 的倍数的最小三位数是()。9 三个连续奇数的和是45,这三个奇数分别是()、()和()。二、仔细推敲、辨析正误。(下列说法你认为正确的打“”,错误的打“”。)12 既是质数也是偶数。()2一个合数最少有3 个因数。()3.因为 369=4,所以 36 是倍数,9 是因数()。4AB=5,所以 A 是 B 的倍数,B 是 A 的因数。()5.在五个连续的自然数中,必有一个是5 的倍数。()6523的个位上是3,所以523是3的倍数。()7所有的质数都是奇数,所有的合数都是偶数。()8一个数是 2 的倍数,又是 5 的倍数,这个数个位上一定是0。()同学们,第二单元的学习已经结束,老师相信你一定又有新的收获吧,快来检验一下吧!9自然数 a 的最大因数是 a,最小倍数也是 a。()10所有的质数加上1 后,就变成了合数。()三、反复比较、慎挑细选。(把正确答案的序号填在括号里。)110 以内既是奇数,也是合数的数是()。9 2 7 229 是()。奇数,也是质数偶数,也是质数合数3某班的学生无论分成6 人一组或4人一组,都刚好分完,则下列()可能是这个班的人数。30 60 40 4100 以内是 3 和 5 的倍数的最大奇数是()。75 90 95 5的和是奇数,一定是()。质数合数奇数偶数6属于因数和倍数关系的等式是()。20.250.5 22550 200 7一个数,它既是12 的倍数,又是 12的因数,这个数是()。6 12 24 144 8两个不同的自然数(0 除外)的公因数一定()公倍数。大于等于小于9最小的合数是()。2 4 9 10.从 0、1、4、5 这四个数字中选择三个不同的数字,组成既是3 的倍数,又是2的倍数的三位教,有()种不同的组法。2 4 3 5 四、细心观察,精确套圈。51 77 13 25 19 88 111 2 57 49 62 23 质数合数奇数偶数文档编码:CL7G1W3L4K9 HC2V8B4H1Z5 ZE7T5R8T1L2文档编码:CL7G1W3L4K9 HC2V8B4H1Z5 ZE7T5R8T1L2文档编码:CL7G1W3L4K9 HC2V8B4H1Z5

ZE7T5R8T1L2五、看清要求,慎重答题。(1)在圈内写上合适的数。60的因数 50以内 6 的倍数(2)从四张数字卡片中选出三张,按要求组成三位数(最少写出个),使它符合题目要求。奇数:偶数:;组成的数是 3 的倍数;组成的数是 5 的倍数;组成的数既是 2 的倍数,又是 3 的倍数;组成的数有因数 2 和 5;六、灵活运用,解决问题。1五年级有 48名同学报名参加义务劳动 老师让他们自己分成人数相等的若干小组,要求组数大于2,小于 10可以分成几组?2.五(1)班 6 名同学去给小树苗浇水,小树苗不到30 棵,他们发现每人浇水棵数相同,这批小树苗可能有多少棵?35 2 8 0 文档编码:CL7G1W3L4K9 HC2V8B4H1Z5 ZE7T5R8T1L2文档编码:CL7G1W3L4K9 HC2V8B4H1Z5 ZE7T5R8T1L2文档编码:CL7G1W3L4K9
