Iabsolutely do not understand these to someone me worth 15 pts

Part 1)

A foot is 12 inches so 5 feet is 60 inches.

First, you have to divide 216 by 18.(miles)



Next, since 5 feet is 60 inches, multiply the quotient by 60.(inches)



The two cities are 720 inches apart on the map.

Part 2)

The ratio to cups of flour to cups of sugar is 3:4

First, divide 7.5 by 3.(flour)



Next, multiply the quotient by 4.(sugar)



You need 10 cups of sugar for the recipe if 7.5 cups of flour is used.

I hope this helps because I spent a lot of time on it c:
