we know that

16/4-----------> 8/2---------> 4/1
so
case 1) 
64/16--------> 32/8-----> 16/4------> 8/2------> 4/1
the quantity (64/16) is proportional to 16/4

case 2)
6/1 is not 4/1
so
the quantity (6/1) is not proportional to 16/4

case 3)
5/1 is not 4/1
so
the quantity (5/1) is not proportional to 16/4

case 4)
48*12--------> 24/6-----> 12/3------> 4/1
the quantity (48/12) is proportional to 16/4

case 5)
4/1 is equal to 4/1
so
the quantity (4/1) is proportional to 16/4
