10－2.65＝      0÷3.8＝       9×0.08＝      24÷0.4＝    67.5＋0.25＝        6＋14.4＝        0.77＋0.33＝

5－1.4－1.6＝       80×0.125=       ÷3× =

二、用简便方法计算下面各题。（90分，4×20＋5×2）

1125－997                                           998+1246                                                4 +3.2＋5 +6.8

12 －(1 +2 )                                       400÷125÷8                                                    25×（37×8）

125×8.8                                 4.35＋4.25＋3.65＋3.75                                                  3.4×99＋3.4

17.15－8.47－1.53                                           17 －3 －4                                             0.125×0.25×32

22.3－2.45－5.3－4.55                   1 4.25－(7+4.25)                          187.7×11－187.7

88×10.1                          2.42÷ +4.58× －4÷3                    2.9+29.9+299.9+2999.9
