a)
3除5分22除11分18
=3÷(22/5)÷(18/11)
=3x(5/22)x(11/18)
=(15/22)x(11/18)
=(5/22)x(11/6)*
=(5/2)x(1/6)*
=5/12

b)
9除22分9乘11分3
=9÷(9/22)x(3/11)
=9x(22/9)x(3/11)
=(22/1)x(3/11)*
=(6/1)*
=6

c)
5分3+5分4除10分8
=3/5+(4/5)÷(8/10)
=3/5+(4/5)x(10/8)
=3/5+(1/1)*
=1 3/5

d)
3又6分5 - 2又2分1乘3分1
=3 5/6-2 1/2x(1/3)
=23/6-(5/2)x(1/3)
=23/6-5/6
=18/6
=3/1*
