小数加减乘除口算题
20 道小数加减乘除口算题一、小数加法1. 0.5 + 0.3 = 0.8-解析：十分位上5 + 3 = 8，个位都是0，所以结果是0.8。
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。

出10道口算题
小数加减法
1. 3.5 +
2.1 = 5.6
解析：小数加法，先把小数点对齐，然后从最低位开始相加。
5加1等于6，3加2等于5，所以结果是5.6。
2.7.2
3.8= 3.4
解析：小数减法，同样先把小数点对齐，从最低位开始减。
2减8不够减，向个位借1当10，12减8等于4，6借走1剩5，5减3等于2，所以结果是3.4。
3. 4.6 + 5.4 = 10
解析：小数点对齐后相加，6加4等于10，向个位进1，4加5加1等于10，所以结果是10。
2.7.2
3.9= 6.4
解析：1减7不够减，向个位借1当10，11减7等于4，8减2等于6，结果是6.4。
5. 5.3 + 3.7 = 9
解析：3加7等于10，向个位进1，5加3加1等于9，结果为9。
整数乘除法
6.25×4 = 100
解析：四五二十，后面再加一个0，所以结果是100。
7.120÷3 = 40
解析：12除以3等于4，后面的0直接落下来，就是40。
8. 36÷9 = 4
解析：四九三十六，所以结果是4。
8.15×6 = 90
解析：先算10乘以6等于60，再算5乘以6等于30，60加30等于90。
9.200÷5 = 40
解析：20除以5等于4，后面两个0直接落下来，结果是40。
