五年级上数学小数点计算题一、小数加法1. 3.5 +2.7 = 6.2解析：小数点对齐，从最低位加起，5+7=12，向前进1，3+2+1=6。

2. 4.8 + 1.6 = 6.4解析：同样小数点对齐，8+6=14，进1，4+1+1=6。

3. 2.34 + 1.56 = 3.9解析：先将百分位4+6=10，进1，十分位3+5+1=9，个位2+1=3。

二、小数减法1. 5.2 - 3.8 = 1.4解析：小数点对齐，2 不够减8 向个位借1，12-8=4，个位4-3=1。

2. 7.6 - 4.9 = 2.7解析：6 减9 不够减向个位借1，16-9=7，个位 6 被借走 1 剩5，5-4=1。

3. 3.56 - 2.13 = 1.43解析：百分位6-3=3，十分位5-1=4，个位3-2=1。

三、小数乘法1. 2.5×3 = 7.5解析：先按整数乘法计算25×3=75，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。

2. 1.2×4 = 4.8解析：12×4=48，因数中有一位小数，结果为 4.8。

3. 0.5×0.6 = 0.3解析：5×6=30，因数中一共有两位小数，结果是0.3。

四、小数除法1. 6.3÷3 =2.1解析：先用 6 除以 3 得2，再用 3 除以 3 得1，商为 2.1。

2. 8.4÷4 = 2.1解析：8 除以 4 得2，4 除以 4 得1，结果是 2.1。

3. 9.6÷6 = 1.6解析：9 除以 6 得 1 余3，36 除以 6 得6，商为 1.6。

五、混合运算1. 5.2 + 3.6×2 = 5.2 + 7.2 = 12.4解析：先算乘法 3.6×2=7.2，再算加法 5.2+7.2=12.4。

2. 8.5 - 2.4÷3 = 8.5 - 0.8 = 7.7解析：先算除法 2.4÷3=0.8，再算减法8.5-0.8=7.7。
