10道五年级上册口算题小数的加减
10道五年级上册口算题小数的加减
嘿,同学们!今天我们来练练小数的加减法口算题哟!
第一题:0.3 + 0.5 = ?这道题很简单呀,就是把 3 个 0.1 和 5 个 0.1
加起来,那就是 8 个 0.1 呀,所以答案就是 0.8 啦!
第二题:1.2 - 0.7 = ?1 可以分成 10 个 0.1 嘛,10 个 0.1 加上 2 个
0.1 就是 12 个 0.1 ,减去 7 个 0.1 ,不就还剩下 5 个 0.1 嘛,所以答案就是 0.5 呀!
第三题:0.8 + 1.3 = ?这就相当于 8 个 0.1 加上 13 个 0.1 咯,那就是 21 个 0.1 呀,也就是 2.1 嘛,是不是很容易呀!
第四题:2.5 - 1.8 = ?2 就是 20 个 0.1 呀,加上 5 个 0.1 就是 25 个
0.1 ,减去 18 个 0.1 ,剩下 7 个 0.1 咯,答案就是 0.7 啦!
第五题:3.6 + 2.1 = ?这就是 36 个 0.1 加上 21 个 0.1 嘛,等于 57
个 0.1 ,那就是 5.7 呀!
第六题:4.2 - 3.5 = ?4 可以看成 40 个 0.1 嘛,减去 35 个 0.1 ,不就剩下 5 个 0.1 嘛,答案就是 0.7 咯!
第七题:5.3 + 3.8 = ?哎呀呀,这就是 53 个 0.1 加上 38 个 0.1 呀,等于 91 个 0.1 ,就是 9.1 嘛!
第八题:6.5 - 4.8 = ?6 是 60 个 0.1 呀,减去 48 个 0.1 ,剩下 12 个
0.1 咯,那就是 1.2 呀!
第九题:7.2 + 4.6 = ?72 个 0.1 加上 46 个 0.1 ,等于 118 个 0.1
呀,就是 11.8 咯!
第十题:8.1 - 5.4 = ?8 可以想成 80 个 0.1 呀,减去 54 个 0.1 ,不就剩下 26 个 0.1 嘛,答案就是 2.6 啦!

小数加减法口算题
小数加减法口算题
一、小数加法口算题
1. 0.3 + 0.4 = 0.7
- 解析:0.3是3个0.1,0.4是4个0.1,3个0.1加上4个0.1等于7个0.1,即0.7。
2. 0.2 + 0.5 = 0.7
- 解析:0.2表示2个0.1,0.5表示5个0.1,它们相加就是7个0.1,结果是0.7。
3. 0.7 + 0.1 = 0.8
- 解析:0.7包含7个0.1,再加上1个0.1,总共就是8个0.1,也就是0.8。
4. 1.2 + 0.3 = 1.5
- 解析:先算小数部分,0.2 + 0.3 = 0.5,再加上整数部分1,结果是1.5。
5. 2.3 + 0.4 = 2.7
- 解析:同样先算小数部分3个0.1加4个0.1得7个0.1,即0.7,再加上整数部分2,得到2.7。
6. 3.1 + 0.6 = 3.7
- 解析:先把小数部分相加,0.1 + 0.6 = 0.7,然后加上整数部分3,结果是3.7。
7. 0.8 + 0.9 = 1.7
- 解析:0.8是8个0.1,0.9是9个0.1,合起来是17个0.1,也就是1.7。
8. 1.5 + 0.4 = 1.9
- 解析:先算0.5 + 0.4 = 0.9,再加上整数部分1,答案是1.9。
9. 2.6 + 0.2 = 2.8
- 解析:小数部分6个0.1加2个0.1为8个0.1,即0.8,加上整数部分2得2.8。
10. 0.7 + 1.2 = 1.9
- 解析:先算0.7 + 0.2 = 0.9,再加上1,结果是1.9。
二、小数减法口算题
11.0.9-90. 3= 0.6
- 解析:0.9里有9个0.1,减去3个0.1,剩下6个0.1,即0.6。
11.0.9-91. 4= 0.3
- 解析:8个0.1减去5个0.1,还剩3个0.1,答案是0.3。
11.0.9-92. 1= 0.6
- 解析:7个0.1减去1个0.1,剩下6个0.1,是0.6。
