2. 1.2 + 0.7 = 1.9-解析:十分位上2 + 7 = 9,个位1 + 0 = 1,结果是1.9。
3. 2.6 + 1.3 = 3.9-解析:十分位上6 + 3 = 9,个位2 + 1 = 3,结果是3.9。
二、小数减法1. 0.8 - 0.3 = 0.5-解析:十分位上8 - 3 = 5,个位都是0,结果是0.5。
2. 1.5 - 0.7 = 0.8-解析:十分位上5 不够减7,向个位借1 当10,15 - 7 = 8,个位0 被借走1 变为-1,结果是0.8。
3. 2.4 - 1.2 = 1.2-解析:十分位上4 - 2 = 2,个位2 - 1 = 1,结果是1.2。
三、小数乘法1. 0.5×0.3 = 0.15-解析:5×3 = 15,两个因数一共有两位小数,所以结果是0.15。
2. 1.2×0.4 = 0.48-解析:12×4 = 48,两个因数一共有两位小数,结果是0.48。
3. 2.5×0.4 = 1-解析:25×4 = 100,两个因数一共有两位小数,结果是1。
四、小数除法1. 0.6÷0.2 = 3-解析:根据除法的性质,6÷2 = 3,所以0.6÷0.2 = 3。
2. 1.2÷0.3 = 4-解析:12÷3 = 4,所以1.2÷0.3 = 4。
3. 2.4÷0.6 = 4-解析:24÷6 = 4,所以2.4÷0.6 = 4。
4. 0.8÷0.4 = 2-解析:8÷4 = 2,所以0.8÷0.4 = 2。
5. 1.5÷0.5 = 36. 2.1÷0.7 = 3-解析:21÷7 = 3,所以2.1÷0.7 = 3。
小数点的加减乘除法计算题
小数点的加减乘除法计算题一、小数加法1. 题目:3.25 +2.1- 解析:- 计算小数加法时,先把小数点对齐,也就是相同数位对齐。
- 然后按照整数加法的方法进行计算。
- 3.25+2.1 = 3.25+2.10 = 5.35。
2. 题目:1.5+0.78- 解析:- 同样先将小数点对齐,1.5 = 1.50。
- 然后相加:1.50+0.78 = 2.28。
二、小数减法1. 题目:5.3 -2.15- 解析:- 先把小数点对齐。
- 从最低位减起,如果哪一位不够减,就从前一位借1当10再减。
- 5.30 - 2.15=3.15。
2. 题目:4.2 -3.98- 解析:- 把4.2写成4.20。
- 相减得:4.20 - 3.98 = 0.22。
三、小数乘法1. 题目:2.5×3.2- 解析:- 按照整数乘法的计算方法算出积,25×32 = 800。
- 再看因数中一共有几位小数,就从积的右边起数出几位,点上小数点。
2.5有一位小数,3.2有一位小数,共两位小数。
- 所以2.5×3.2 = 8.00 = 8。
2. 题目:0.35×0.4- 解析:- 先算35×4 = 140。
- 因数0.35有两位小数,0.4有一位小数,共三位小数。
- 从积的右边起数出三位点上小数点,得到0.140 = 0.14。
四、小数除法1. 题目:6.25÷2.5- 解析:- 除数是小数的除法,先把除数转化成整数。
除数2.5扩大10倍变成25,被除数6.25也扩大10倍变成62.5。
- 然后按照除数是整数的除法进行计算,62.5÷25 = 2.5。
2. 题目:0.78÷0.3- 解析:- 把除数0.3扩大10倍变为3,被除数0.78也扩大10倍变为7.8。
- 计算7.8÷3 = 2.6。
五年级上册小数乘除法口算
20道五年级上册小数乘除法口算题一、小数乘法1. 2.5×4=10-解析:先计算25×4=100,然后因为2.5 有一位小数,从积的右边起数一位点上小数点,结果是10。
2. 1.2×3=3.6-解析:先计算12×3=36,1.2 有一位小数,从积的右边起数一位点上小数点,得3.6。
3. 0.5×6=3-解析:5×6=30,0.5 有一位小数,点上小数点后结果是3。
4. 3.2×2=6.4-解析:32×2=64,3.2 有一位小数,结果是6.4。
二、小数除法5. 4.8÷2=2.4-解析:48÷2=24,4.8 是一位小数,商也应是一位小数,为2.4。
6. 6.3÷3=2.1-解析:63÷3=21,6.3 有一位小数,商是2.1。
7. 9.6÷4=2.4-解析:96÷4=24,9.6 有一位小数,结果是2.4。
8. 8.4÷2=4.2-解析:84÷2=42,8.4 有一位小数,商是4.2。
三、混合运算9. 2.4×3÷2=3.6-解析:先算2.4×3=7.2,再算7.2÷2=3.6。
10. 1.5×4÷3=2-解析:1.5×4=6,6÷3=2。
11. 3.6×2÷4=1.8-解析:3.6×2=7.2,7.2÷4=1.8。
12. 2.7×3÷9=0.9-解析:2.7×3=8.1,8.1÷9=0.9。
四、稍复杂的小数乘除法13. 4.5×1.2=5.4-解析:先算45×12=540,4.5 和1.2 一共有两位小数,从积的右边起数两位点上小数点,结果是 5.4。
14. 3.6×1.5=5.4-解析:36×15=540,3.6 和1.5 一共有两位小数,结果是5.4。
