8÷8÷數(shù)學(xué)公式=數(shù)學(xué)公式+0.37=10-1數(shù)學(xué)公式1-9.9%            
1數(shù)學(xué)公式:2數(shù)學(xué)公式99099÷99       數(shù)學(xué)公式+數(shù)學(xué)公式×4300×0.3%
1%÷10%0.1×0.01÷0.1.

8÷8÷=8,+0.37=0.995,10-1=81-9.9%=0.901,
1:2=99099÷99=1001,+×4=1300×0.3%=0.9,
1%÷10%=0.1,0.1×0.01÷0.1=0.01.


分析:8÷8÷按照從左到右的順序計算;+0.37先把分數(shù)化成小數(shù),然后計算;1:2求比值用比的前項除以比的后項即可;+×4先算乘法,再算加法;
0.1×0.01÷0.1運用乘法結(jié)合律簡算;其它題目根據(jù)運算法則直接求解.
點評:本題考查了基本的運算,計算時要細心,注意計算的準確率.
