1÷2/1÷3/2÷4/3÷5/4÷6/5÷7/6÷8/7÷9/8÷10/9=1×2×2/3×4/5×5/6×6/7×7/8×8/9×9/10=1×10=10
25*6.4*12.5=(25x4x4)x(0.8x12.5)=400x10=4000(3-1/4-5/12)÷2/3=3x3/2-1/4x3/2-5/12x3/2=9/2-3/8-5/8=9/2-1
1.25÷0.58-0.32×0.58=﹙1.25-0.32﹚×0.58=0.93×0.58=﹙1-0.07﹚×0.58=0.58-0.07×0.58=0.58-0.0406=0.5394.
9^20÷27^10÷3^7=3^40÷(3^30×3^7)=3^40÷3^37=3^3=27

=3.1÷6.2×10的(16-6)次方=0.5×10的10次方=5×10的5次方
9.3÷3.1×2.5=3×2.5=7.5再问:5.6×5.8÷2.9的简便计算
(60/10)*(10/3)=203/10*(1/6)=1/2020-1/20=19+1-1/20=19+19/2019又20/19
[17.1-17.2÷(3.1-0.7)]×0.6=[17.1-17.2÷2.4)]×0.6=17.1×0.6-17.2÷(2.4/0.6)=10.26-4.3=5.96
原式=1+1/6+1/12+1/20+1/30+1/42+...+1/10100=1+1/2-1/3+1/3-1/4+1/4-1/5+1/5-1/6+1/6-1/7+...+1/100-1/101=1
6.12÷8.5-0.58=(6.12-0.58*8.5)÷8.5=(6.12-4.93)÷8.5=1.19÷8.5=0.14
