Answer:
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

Answer:
60 miles
Step-by-step explanation:
So if 1 inch = 12 miles, you need to find 4 inches. There are multiple ways to achieve this. However ratios/proportions might be easiest.
if 1/12 = 4/x, x is the value of miles. Cross multiply so you get this:
1 4
- = - = 60 = x
12 x
If x equals 60, that means that 4 inches equals 60 miles on the map.
You could also just find an equal fraction by multiplying the top and bottom both by 4.
