计算：[1/20+(1-0.28)÷9/10]÷11/2
计算：[1/20+(1-0.28)÷9/10]÷11/2
[1/20+(1-0.28)÷9/10]÷11/2
=(1/20+0.72*10/9)(2/11)
=(1/20+0.8)(2/11)
=17/110
[1/20+(1-0.28)÷9/10]÷11/2
=【1/20+0.72÷0.9】×2/11
=[17/20]×2/11
=17/110
[1/20+(1-0.28)÷9/10]÷11/2
=(1/20+0.72×10/9)×2/11
=(1/20+0.8)×2/11
=0.85×2/11
=17/110
[1/20+(1-0.28)÷9/10]÷11/2
=[1/20+(1-7/25)*10/9]*(2/11)
=[1/20+(18/25)*10/9]*(2/11)
=[1/20+4/5]*(2/11)
=(17/20)*(2/11)
=17/110
=[1/20+0.72÷0.9]÷5.5
=[0.05+0.8]÷5.5
=0.85÷5.5
