12.60*7.6*2.32/(1.9*1.4*2.9)的简便算法
12.60*7.6*2.32/(1.9*1.4*2.9)的简便算法

12.60*7.6*2.32/(1.9*1.4*2.9)的简便算法
12.60*7.6*2.32/(1.9*1.4*2.9)
= 12.60*7.6*2.32/(1.9*1.4*2.9)
= 9 * 4 * 0.8
= 28.8

原式=(12.6/1.4) *(7.6/1.9)*(2.32/2.9)=9*4*0.8=28.8

12.60×7.6×2.32÷(1.9×1.4×2.9)
=12.60×7.6×2.32÷(1.4×1.9×2.9)
=(12.60÷1.4)×(7.6÷1.9)×(2.32÷2.9)
= 9× 4 × 0.8
= 28.8
