5.61乘9.9乘0.38除(0.19乘3又10分之3乘1.1)等于多少

5.61乘9.9乘0.38除(0.19乘3又10分之3乘1.1)等于多少
5.61乘9.9乘0.38除(0.19乘3又10分之3乘1.1)
=5.61x9x1.1x0.19x2÷(0.19x3.3x1.1)
=5.61x9x2÷3.3
=5.5x1.1x3x2÷3.3
=5.5x2
=11

=5.61x9x1.1x0.19x2÷(0.19x3.3x1.1)
=5.61x9x2÷3.3
=5.5x1.1x3x2÷3.3
=5.5x2
=11

5.61*9.9*0.38/[0.19*1.1*(33/10)]
=0.38/0.19 * 9.9/1.1 *5.61/(33/10)
=2* 9 *1.7
=30.6

*=乘号,/=除号,(3+3/10)=3又10分之3
5.61*9.9*0.38/(0.19*(3+3/10)*1.1)
=5.61*9.9*0.38/(0.19*3.3*1.1)
=21.10482/0.6897
=30.6
另一种算法:
5.61*9.9*0.38/(0.19*(3+3/10)*1.1)
=5.61*9.9*0.38/(0...

全部展开

*=乘号,/=除号,(3+3/10)=3又10分之3
5.61*9.9*0.38/(0.19*(3+3/10)*1.1)
=5.61*9.9*0.38/(0.19*3.3*1.1)
=21.10482/0.6897
=30.6
另一种算法:
5.61*9.9*0.38/(0.19*(3+3/10)*1.1)
=5.61*9.9*0.38/(0.19*3.3*1.1)
两边约去1.1,0.19
=5.61*9*2/3.3
再约去3.3
=5.1*3*2
=30.6
