Part 1)
A foot is 12 inches so 5 feet is 60 inches.
First, you have to divide 216 by 18.(miles)
[tex]216/18=12[/tex]
Next, since 5 feet is 60 inches, multiply the quotient by 60.(inches)
[tex]12*60=720[/tex]
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)
[tex]7.5/3=2.5[/tex]
Next, multiply the quotient by 4.(sugar)
[tex]2.5*4=10[/tex]
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:
