6.6*7.5*4.8/(4.4*3.3*2.5) 简便计算

6.6*7.5*4.8/(4.4*3.3*2.5) 简便计算
6.6*7.5*4.8/(4.4*3.3*2.5) 简便计算

6.6*7.5*4.8/(4.4*3.3*2.5) 简便计算
=(6.6/3.3)*(7.5/2.5)*(4.8/4.4)=2*3*(12/11)=72/11

6.6*7.5*4.8/(4.4*3.3*2.5)=(6.6/4.4)*(7.5/2.5)*(4.8/3.3)=(3/2)*3*(16/11)=72/11

(7.5/2.5)*((6*1.1)/(4*1/1))*(4*1.2)/(3*1.1)=
(3)*(6)*(1.2)/(1.1*3)=72/11

=(6.6/3.3)*(7.5/2.5)*4.8/4.4
=2*3*4.8/4.4
=78/11

6.6*7.5*4.8/(4.4*3.3*2.5)
=6.6/3.3*7.5/2.5*4.8/4.4
=2*3*48/44
=3*48/22
=3*24/11
=72/11
