- 然后从最低位加起，公式，满十进一，在百分位写0，向十分位进1。
- 十分位上公式，满十进一，在十分位写0，向个位进1。
- 个位上公式，结果是公式，小数末尾的0可以去掉，结果为5。
二、小数减法计算题1. 题目- 公式- 解析：- 把小数点对齐，相同数位相减。
- 先算十分位，公式。
- 再算个位，公式，结果是公式。
2. 题目- 公式- 解析：- 小数点对齐后。
- 先从百分位减起，公式。
- 再算十分位，公式。
- 最后算个位，公式，结果是公式。
三、小数乘法计算题1. 题目- 公式- 解析：- 按照整数乘法的计算方法计算，公式。
- 因数公式有一位小数，因数公式有一位小数，一共两位小数。
- 从积的右边起数出两位点上小数点，结果是公式，小数末尾的0可以去掉，结果为8。
2. 题目- 公式- 解析：- 先算公式。
- 因数公式有两位小数，因数公式有一位小数，共三位小数。
- 从积的右边起数出三位点上小数点，结果是公式，也就是1。
四、小数除法计算题1. 题目- 公式- 解析：- 根据商不变的性质，把被除数和除数同时扩大10倍，变成公式。
- 先看被除数的前两位，公式。
- 再把余数12和个位上的5组成125，公式。
- 结果是2.5。
2. 题目- 公式- 解析：- 把被除数和除数同时扩大10倍，变为公式。
- 公式，所以结果是7。
