3.92×5.1≈	53.1÷0.89≈	7.01×2.78≈	90.01÷0.89≈

Answer 1

分析 根據(jù)四則運(yùn)算的計算法則計算即可求解．

解答 解：

2.2×0.5=1.1	7.6÷0.76=10	1.25×8=10	3.4×60=204
36×0.04=1.44	4.2÷0.14=30	8÷1.6=5	6.7+3=9.7
60-0.58=59.42	0.03×0.6=0.018	1÷5=0.2	1.3×0.2=0.26
3.92×5.1≈20	53.1÷0.89≈60	7.01×2.78≈21	90.01÷0.89≈100

點評 考查了四則運(yùn)算，關(guān)鍵是熟練掌握計算法則正確進(jìn)行計算．
