希望对你有帮助。
一、口算
1.2+3.2+0.8 = 5.2 1.2×2.5×4 = 12 3.01+1.7+0.99 =5.7
1×0.66÷6 = 0.11 2.7-2.7÷2.7 = 1.7 0.1-0.0...
全部展开
一、口算
1.2+3.2+0.8 = 5.2 1.2×2.5×4 = 12 3.01+1.7+0.99 =5.7
1×0.66÷6 = 0.11 2.7-2.7÷2.7 = 1.7 0.1-0.047 =0.053
0.29÷2.9 = 0.001 3.4×0.2 = 0.68 0.57÷19 =0.03
二、用递等式计算,能简便的要用简便方法计算.
1.93+2.7+2.07+7.3 (0.25+2.5+25)×0.4
5-0.9×0.2+1.8÷0.5 [0.783+0.75×(0.55-0.15)]÷19
6.4×3.28+4.6×3.28-3.28 0.78×99+0.78
三、求未知数x
0.56×x = 8.4 62.1÷x = 0.03
x+0.92 = 1.2 3.02-x = 0.98
四.、列式计算
1、5.46与7.86的和, 除以0.4, 商是多少?
2、 一个数的1.5倍是3.75,这个数的2.4倍是多少?
3、3.7乘6.04与0.17的差,积是多少?
其他项目就不要答案了吧 很简单的啊
