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,

Answer 1

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%)
