4.5*11.1*4.8/(33.3*0.8*0.9)这道题怎样简算?

4.5*11.1*4.8/(33.3*0.8*0.9)这道题怎样简算?
4.5*11.1*4.8/(33.3*0.8*0.9)
=1.5*11.1*4.8/(11.1*0.8*0.9)
=1.5*11.1*6/(11.1*1*0.9)
=11.1*9/(11.1*1*0.9)
=10

4.5*11.1*4.8/(33.3*0.8*0.9)
=5*6/3=10

不会

4.5*11.1*4.8/(33.3*0.8*0.9)
=1.5*11.1*4.8/(11.1*0.8*0.9)
=1.5*11.1*6/(11.1*1*0.9)
=11.1*9/(11.1*1*0.9)
=10

4.5*11.1*4.8/(33.3*0.8*0.9)
=5*6/3
=10
