3.5 小数除以小数(2)
1.填一填。
(1)把被除数和除数同时乘以或除以一个()的数(0除外),()不变,这叫做商不变的性质。
(2)计算37.8÷2.1时,可以把算式看做(),根据商不变的性质,即可算出得数()。
(3)除数是小数的除法,先移动()的小数点,使它变成(),()
的小数点向右移动几位,()的小数点也向右移动几位,位数不够的,在被除数的末尾用()来补足。
(4)除数扩大到原来的100倍,被除数也扩大到原来的100倍,商()。
2.先计算,再说一说你发现了什么。
(1)125÷5= 125÷0.5=
(2)6.8÷34= 6.8÷0.34=
(3)16.8÷1= 16.8÷2.4=16.8÷0.24=
我发现了:
答案
1.(1)相同商(2)378÷21 18
(3)除数整数除数被除数 0 (4)不变
2.(1) 25 250 (2) 0.2 20 (3) 16.8 7 70
我发现了:两个数相除,当除数大于1时,商小于被除数;当除数小于1时,商大于被除数;当除数等于1时,商等于被除数。
