=(55-0.1)*0.38=20.9-0.038=20.862

0.38*54.9 =0.38*(55-0.1) =0.38*55-0.38*0.1 =20.9-0.038 =20.862还不如直接计算

54.9*0.38 =(50+5-0.1)*0.38 =19+1.9-0.038 =20.862

=55*0.38-0.1*0.38 =50*0.38+5*0.38-0.038 =19+1.9-0.038 =20.9-0.038 =20.862

54.9*0.38 =(55-0.1)*0.38 =55*0.38-0.1*0.38 =20.9-0.038 =20.862 你好,本题已解答,如果满意 请点右下角“采纳答案”.

54.9*0.38 =55*0.38-0.1*0.38 =20.9-0.038 =20.862

20.862 解析: 54.9*0.38 =(55-0.1)*0.38 =55*0.38-0.1*0.38 =20.9-0.038 =20.862

解: 54.9*0.38 =(55-0.1)*(0.4-0.02) =55*0.4-55*0.02-0.1*0.4+0.1*0.02 =22-1.1-0.04+0.002 =20.862

(55-0.1)*0.38 =55*0.38-0.038 =20.9-0.038 =20.862

55*0.4=22
