二道简算题怎么做
81.23-40.5/0.81*1.075=?
36.47*109-0.9*364.7=?
二道简算题怎么做81.23-40.5/0.81*1.075=?36.47*109-0.9*364.7=?
81.23-(40.5/0.81)*1.075=81.23-50*1.075= 27.48
36.47*109-0.9*364.7=36.47*109-9*36.47=36.47*(109-9)=3647
(1)81.23-(40.5/0.81)*1.075=81.23-50*1.075= 27.48
(2)36.47*109-9*36.47=36.47*(109-9)=3647
