数学的简算,一定要简算,不然别答,想要分的来,要过程3/5÷11/15÷4÷3/51/2÷8*4/51/3÷（10/33÷2)4/5-4/15+1/55*9/17÷27/34÷1/43/18*3/4÷1/9÷3/4我才5年级,还没学乘除法

Answer 1

3/5÷11/15÷4÷3/5
=3/5*15/11*1/4*5/3
=3/5*5/3*15/11*1/4
=1*15/11*1/4
=15/44
1/2÷8*4/5
=1/2*1/8*4/5
=1/8*2/5
=1/20
1/3÷（10/33÷2)
=1/3÷（10/66)
=1/3*66/10
=22/10
=11/5
4/5-4/15+1/5
=4/5+1/5-4/15
=1-4/15
=11/15
5*9/17÷27/34÷1/4
=5*9/17*34/27*4
=9/17*34/27*20
=9*2/27*20
=2/3*20
=40/3
3/18*3/4÷1/9÷3/4
=3/18*3/4*9*4/3
=3/18*9*3/4*4/3
=3/2*1
=3/2
