分析:運(yùn)用小數(shù)的乘法的計(jì)算法則進(jìn)行計(jì)算即可.
解答:
解:8×0.5=0.4
0.83÷0.1=8.3
0.44÷2.2=0.2
0.6×0.5=0.03
0.56÷8=0.07
0.42÷0.7÷0.6=1
12.5×18.5×0.8=185
1.25×8=10
0.74×0.6+0.74×0.4=0.74
5.38+0.45+1.55=7.38
0.4+0.15=0.55.
故答案為:0.4,8.3,0.2,0.03,0.07,1,185,10,0.74,7.38,0.55.
點(diǎn)評(píng):本題考查了小數(shù)的乘法的計(jì)算法則,注意小數(shù)點(diǎn)的位置.
