五年级小数点口算题
人教版五年级上册口算题卡
人教版五年级上册口算题卡一、小数乘法部分1. 题目：0.5×0.3 =解析：计算小数乘法时，先按照整数乘法的方法计算，5×3 = 15。
然后看因数中一共有两位小数，就从积的右边起数出两位点上小数点，所以结果是0.15。
2. 题目：1.2×0.4 =解析：先算12×4 = 48，因数共有两位小数，从积的右边起数两位点上小数点，得到0.48。
3. 题目：0.6×0.8 =解析：6×8 = 48，因数中一共有两位小数，结果为0.48。
二、小数除法部分1. 题目：0.6÷0.3 =解析：根据商不变的性质，把被除数和除数同时扩大10倍，变成6÷3 = 2。
2. 题目：1.2÷0.4 =解析：同样将被除数和除数同时扩大10倍，变为12÷4 = 3。
3. 题目：0.8÷0.2 =解析：被除数和除数同时扩大10倍得8÷2 = 4。
三、简易方程部分（用字母表示数相关的简单计算）1. 题目：如果a = 3，那么2a+5 =解析：把a = 3代入式子2a+5中，得到2×3+5 = 6 + 5 = 11。
2. 题目：当x = 4时，3x 2 =解析：将x = 4代入式子3x 2，3×4 2 = 12 2 = 10。
四、多边形的面积部分（简单的边长与面积计算相关口算）1. 题目：一个平行四边形的底是5厘米，高是3厘米，它的面积是多少平方厘米？解析：平行四边形的面积 = 底×高，即5×3 = 15平方厘米。
2. 题目：三角形的底是4厘米，高是2厘米，面积是多少平方厘米？解析：三角形面积 = 底×高÷2，4×2÷2 = 4平方厘米。

五年级数学上册第一单元口算题
五年级数学上册第一单元口算题
一、小数乘法口算题。
1. 0.2×5=
解析：根据小数乘法的意义，0.2×5表示5个0.2相加，0.2 + 0.2+0.2 + 0.2+0.2 = 1，也可以先算2×5 = 10，然后看因数中一共有一位小数，从积的右边起数出一位点上小数点，所以结果是1。
2. 0.3×4=
解析：0.3×4表示4个0.3相加，0.3+0.3 + 0.3+0.3 = 1.2，或者先算3×4 = 12，因数中有一位小数，所以积是1.2。
3. 1.2×3=
解析：先算12×3 = 36，因数1.2有一位小数，从积的右边起数出一位点上小数点，结果是3.6。
4. 2.5×2=
解析：25×2 = 50，因数2.5有一位小数，积为5.0，也就是5。
二、小数除法口算题（除数是整数）
1. 0.6÷2=
解析：把0.6看作6个0.1，6个0.1平均分成2份，每份是3个0.1，即0.3。
也可以按照整数除法计算6÷2 = 3，被除数是一位小数，商也是一位小数，所以结果是0.3。
2. 1.5÷3=
解析：15÷3 = 5，被除数1.5是一位小数，商就是0.5。
3. 2.4÷4=
解析：24÷4 = 6，因为被除数是一位小数，所以商0.6。
4. 3.6÷6=
解析：36÷6 = 6，被除数3.6有一位小数，商为0.6。
