一、计算：
1、竖式计算（得数精确到百分位）
8.63×0.42
0.38×2.6
2、脱式计算（能简算的要简算）。
0.125×0.25×8×4
7.4×0.28+0.28×2.6
4.8×0.9+0.48
（4－0.4）×2.5
[（5.1－3.6）÷0.8－1]×0.09
2．（77.4－3.096÷0.4）÷0.03
3．30.1÷[（6.07＋2.53）×0.7]
4．0.94×2.5＋0.094×75
5．98.4×98＋98.4×2
6．9.28×13－9.28×4＋9.28
7．97.2÷[（54.8＋45.2）×（6－5.46）]
8．1.25×32
[8.5-（3.6+3.6）]
÷2.6
10.1×87
1.4×[（7.5+38.4）÷0.9]
