怎样简便计算4.68*35.1+46.8*5.34+0.468*115
观察三个数,它们有相同的468,所以可以配成相同的数,再提出来.
4.68*35.1+46.8*5.34+0.468*115
=4.68*35.1+4.68*53.4+4.68*11.5
=4.68*(35.1 + 53.4 + 11.5)
=4.68 * 100
=468
4.68*35.1+46.8*5.34+0.468*115
=468*0.351+468*0.534+468*0.115
=468*(0.351+0.534+0.115)
=468*1
=468
给分!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
