9.6/(1+88.2%)和7.5/(1+27.1%)如何快速判断大小,有哪些好方法,

9.6/(1+88.2%) ÷ 7.5/(1+27.1%)
= 9.6/(1+88.2%) × (1+27.1%)/7.5
= 9.6/1.882 × 1.271/7.5
= (9.6 × 1.271) / (7.5 × 1.882)
= (96×1271) / (75×1882)
= (48×1271) / (75×941)
= (16×1271) / (25×941)
= 20336 / 23525
< 1
∴
9.6/(1+88.2%) < 7.5/(1+27.1%)还有没有更快的解决办法 ，最好是一眼便知，5-10秒之内。只能除,没他法
