五年级下口算题卡

五年级下口算题卡一、小数乘法部分（1 - 5题）1. 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. 0.25×4 =- 解析：25×4 = 100，因数中有两位小数，所以结果是1.00，小数末尾的0可以去掉，答案是1。

3. 1.2×0.8 =- 解析：先算12×8 = 96，因数共有两位小数，从积的右边起数出两位点上小数点，结果是0.96。

4. 0.18×0.5 =- 解析：18×5 = 90，因数共有三位小数，所以结果是0.090，小数末尾的0可以去掉，为0.09。

5. 2.5×0.4 =- 解析：25×4 = 100，因数共有两位小数，结果是1。

二、分数加减法部分（6 - 10题）6. (1)/(2)+(1)/(3)=- 解析：先通分，2和3的最小公倍数是6，(1)/(2)=(3)/(6)，(1)/(3)=(2)/(6)，然后相加(3)/(6)+(2)/(6)=(5)/(6)。

7. (3)/(4)-(1)/(4)=- 解析：分母相同的分数相减，分母不变，分子相减，3 - 1 = 2，所以结果是(2)/(4)，约分后为(1)/(2)。

8. (2)/(5)+(1)/(10)=- 解析：5和10的最小公倍数是10，(2)/(5)=(4)/(10)，(4)/(10)+(1)/(10)=(5)/(10)，约分后为(1)/(2)。

9. (5)/(6)-(2)/(3)=- 解析：6和3的最小公倍数是6，(2)/(3)=(4)/(6)，(5)/(6)-(4)/(6)=(1)/(6)。

10. (1)/(3)+(1)/(6)=- 解析：3和6的最小公倍数是6，(1)/(3)=(2)/(6)，(2)/(6)+(1)/(6)=(3)/(6)，约分后为(1)/(2)。

五年级暑假口算题卡

五年级暑假口算题卡一、口算题。

1. 0.3 + 0.7 =- 解析：小数加法，将小数点对齐，然后按照整数加法的方法计算，3 + 7 = 10，满十进一，结果是1.0，也就是1。

2. 1.2 - 0.5 =- 解析：小数减法，小数点对齐，从低位减起，2 - 5不够减，从1借1当10，12 - 5 = 7，1被借走1还剩0，所以结果是0.7。

3. 3.6×0.5 =- 解析：先按照整数乘法计算36×5 = 180，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，结果是1.8。

4. 4.8÷0.6 =- 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48÷6 = 8。

5. (1)/(2)+(1)/(3)=- 解析：先通分，找到2和3的最小公倍数是6，(1)/(2)=(3)/(6)，(1)/(3)=(2)/(6)，然后相加(3)/(6)+(2)/(6)=(5)/(6)。

6. (3)/(4)-(1)/(2)=- 解析：先把(1)/(2)化为(2)/(4)，然后相减，(3)/(4)-(2)/(4)=(1)/(4)。

7. 2(1)/(5)+1(3)/(5)=- 解析：先把带分数化为假分数，2(1)/(5)=(11)/(5)，1(3)/(5)=(8)/(5)，相加得(11)/(5)+(8)/(5)=(19)/(5)=3(4)/(5)。

8. 3(1)/(4)-2(1)/(2)=- 解析：化为假分数，3(1)/(4)=(13)/(4)，2(1)/(2)=(5)/(2)=(10)/(4)，相减得(13)/(4)-(10)/(4)=(3)/(4)。

9. 0.25×40 =- 解析：25×40 = 1000，因数中有两位小数，结果是10。

10. 1.5×0.2 =- 解析：先算15×2 = 30，因数共有两位小数，结果是0.3。
