分析:根据小数四则运算的计算方法,计算得解.
解答:
解:8.35-1.25=7.1, | 12.62+3.42=16.04, | 9.16-3.26=5.9, |
6.2+1.8=8, | 18-1.47=16.53, | 80×0.125=10, |
3.7×2=7.4, | 0.25×16=4, | 33+7.69=40.69, |
0.48÷0.01= | 1.25×8=10, | 3.6÷0.6=6, |
9.1÷0.07=130, | 0.72÷12=0.06, | 0.9×0.1=0.09, |
2.01+3.9=5.91, | 0÷0.1×29=0, | 0.7×0.04=0.028. |
点评:此题考查小数四则运算的计算方法的灵活运用,要注意得数的小数点的位置.
