101×0.45的简便计算:101×0.45 =(100+1)x0.45 =100x0.45+0.45 =45+0.45 =45.45
101x0.45简便方法:101×0.45 =(100+1)×0.45 =100×0.45+1×0.45 =45+0.45 =45.45
101×0.45的简便计算:101×0.45 =(100+1)x0.45 =100x0.45+0.45 =45+0.45 =45.45
101x0.45简便方法:101×0.45 =(100+1)×0.45 =100×0.45+1×0.45 =45+0.45 =45.45
101 × 0.45 可以将101 拆解成(100+1),然后可以得到以下算式:101 × 0.45 =(100 + 1)×0.45 = 100 × 0.45 + 1 × 0.45 = 45 + 0.45 = 45.45
100×0.45+0.45 =450+0.45 =495
101×0.45的简便计算? -
解:根据已知条件,采用凑整或者拆分的方法进行简便运算101x0.45 =(100+1)x0.45 =100x0.45+0.45 =45+0.45 =45.45
101*0.45 =(100+1)*0.45 =100*0.45+1*0.45 =45+0.45 =45.45
101×0.45简便运算(递等式)? -
101×0.45 =100×0.45+1×0.45 =45+0.45 =45.45
第一步:观察等式,发现101可转换为100+1。如图:第二步:将101=100+1代入原等式中,即:101×0.24=(100+1)×0.24。如图:第三步:去括号。将100、1分别乘以0.24。如图:第四步:分别计算100×0.24和1×0.24,得出结论为:45+0.45。如图:第五步:将第四步得出的结果进行相加。得出后面会介绍。
