(4/7x6/11x7/8)除以(2/7x3/11x7/16)怎样简便计算
(4/7x6/11x7/8)除以(2/7x3/11x7/16)
即：
(4/7x6/11x7/8)/(2/7x3/11x7/16)
=(4*6*7/(7*11*8))/(2*3*7/(7*11*16))
=(4*3*2*7/(7*11*4*2))/(2*3*7/(7*11*2*8))
=(3/11)/(3/(11*8))
=(3/11)*(11*8/3)
=3*11*8/(11*3)
=8
(4/7x6/11x7/8)除以(2/7x3/11x7/16)
即：
(4/7x6/11x7/8)/(2/7x3/11x7/16)
=(4*6*7/(7*11*8))/(2*3*7/(7*11*16))
=(4*3*2*7/(7*11*4*2))/(2*3*7/(7*11*2*8))
=(3/11)/(3/(11*8))
=(3/11)*(11*8/3)
=3*11*8/(11*3)
=8
