数学五年级上册一个数除以小数的计算练习题(含答案)
3 一个数除以小数的计算本课导学知识点:理解和掌握除数是小数的除法计算法则，能正确地计算除数是小数的除法。
在下面括号里填上适当的数。
3.6÷1.2=（ ）÷12=（ ）87÷0.03=（ ）÷3=（ ）375÷0.25=（ ）÷25=（ ）列竖式计算。
43.5÷2.9= 18.9÷2.7=特别提醒:要计算除数是小数的除法，先移动除数的小数点，使它变成整数。
除数的小数点向右移动几位，被除数的小数点也向右移动几位。
然后按照除数是整数的小数除法进行计算。
【快乐训练营】 一、把下面各题变成被除数是整数的除法。
0.95÷0.005=（ ）÷（ ）1.2 ÷0.03=（ ）÷（ ）0.54÷0.18=（ ）÷（ ）542.5÷17.5=（ ）÷（ ）5.28÷1.2=（ ）÷（ ） 二、想一想，填一填。
1.两个数的商是2.1，如果被除数和除数同时扩大10倍，商是（ ）;如果被除数扩大100倍，要使商不变，除数应（ ）。
2.根据276÷23=12填空。
2.76÷0.23 =（ ） 0.276÷0.023=（ ）27.6÷0.23=（ ） 27.6÷2.3=（ ）三、判断对错。
（对的打√，错的打×）1.在小数除法中，如果被除数缩小为原来的101，则商一定缩小为原来的101。
（ ） 2.计算小数除法时,小数点的移动是以除数的小数位数为标准的。
（ ） 3.84÷0.01实际就是把84扩大到原来的100倍. （ ）4.两个数相除的商是10.4，被除数和除数的小数点都向左移动一位，商就变成了1.04。
（ ）四、选择。
（将正确答案的序号填在括号里）1.被除数扩大到原数的100倍，要使商不变，除数（）。

有快速验算的办法吗？
2.4÷0.04=60
商不变性质：
被除数和除数同时乘或除以一个相同 的数（0除外），商不变。
规律：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。

要使3.2×5.1+3.2×4.8的计算简便，应该应用什么律？
A. 乘法分配律
B. 乘法结合律
C. 乘法交换律
原来两数相除的商是0.25，要使商变成整数，下面正确的方法是？
A. 除数不变，被除数扩大100倍。
B. 除数和被除数同时扩大100倍。
C. 被除数不变，除数扩大100倍。
现在有76吨沙，用一辆4.5吨的货车来运，至少需要几次才能运完？
A. 15
B. 16
C. 17
两数的积是4.68，一个数是1.2，另一个数是（）
A. 0.39
B. 3.9
C. 390
判断：
一个数除以0.97得到的商一定比原数大。
一个数（0除外）除以大于1的数，商比原来的数小。
3.2÷0.12，商是26，余数是8。
小数除法的商都小于被除数。
在小数除法中，如果被除数缩小为原来的十分之一，则商一定缩小为原来的十分之一．
填空：
把36.8平均分成16份，每份是（），37.5除以6的商是（）。
把一个小数的小数点向左移动一位，再除以原小数，商是（）。
