11/24乘8/11+2/5除以4/7
=11/24*8/11+2/5*7/4
=1/3+7/10
=10/30+21/30
=31/30
3/4除以(5-6乘2/3)
=3/4÷(5-4)
=3/4
(5乘3/8-5/8乘2)除以7/8
=5/8(3-2)×8/7
=5/8*8/7
=5/7追问最后一个?追答最后一个怎么了?追问=5/8(3-2)×8/7
bumingbai追答(5乘3/8-5/8乘2)除以7/8
=(5*3/8-5*2/8)÷7/8
=5/8(3-2)×8/7
=5/8*8/7
=5/7
=11/24*8/11+2/5*7/4
=1/3+7/10
=10/30+21/30
=31/30
3/4除以(5-6乘2/3)
=3/4÷(5-4)
=3/4
(5乘3/8-5/8乘2)除以7/8
=5/8(3-2)×8/7
=5/8*8/7
=5/7追问最后一个?追答最后一个怎么了?追问=5/8(3-2)×8/7
bumingbai追答(5乘3/8-5/8乘2)除以7/8
=(5*3/8-5*2/8)÷7/8
=5/8(3-2)×8/7
=5/8*8/7
=5/7
