一。填空题
既是2和5的倍数，又是3的倍数的最小三位数是（30 ）。
2.把3米长的丝带平均分成5粉，每份是这条丝带的（1/5 ），是（3/5 ）米。
3.分数单位是1/8的最简真分数有（4 ），它们的和是（2）。
二.判断题。
1.一个数的倍数一定大于它的因数（× ）。
2.两个质数的积一定是合数。（ √）
3.因为3/9=1/3，所以这两个分数单位也相同。（× ）
4.4米的1/5和1米的4/5相等。（√ ）
5.18的最大因数和最小倍数相等。（ √）
三.选择题。将正确答案的序号填在括号里。
假分数一定（C ）。 A.大于1 B.小于1 C.大于1或等于1
2.一个最简分数，把它的分子扩大到原来的2倍，分数缩小到原来的1/2，这个分数值（ B） A.扩大到原来的4倍 B.缩小到原来的1/4 C.不变
3.两个不同质数最大公因数是（A ）。 A.1 B.小数 C.大数
四解决问题
1.小萍做语文作业用了1/2小时，做数学作业比做语文作业少用了1/4小时。
（1）小萍做数学作业用了多少小时？1/2-1/4=1/4小时
（2）小萍做两种作业一共用了多少小时？1/2+1/4=3/4小时
2.甲汽车28分钟行20千米，乙汽车40分钟行25千米。按每分钟的速度算，哪一辆汽车的速度快？ 20/28=5/7 25/40=5/8 5/7>5/8，甲车快
3.一本科技书，小亮看了60页，还剩下40页没有看。
（1）看了的页数占这本书总页数的几分之几？60/（60+40）=3/5
（2）没有看的页数占这本书总页数的几分之几？40/（60+40）=2/5
