If 2/3 inch on a map corresponds to an actual distance of 9 miles, what distance on the map will represent 21 miles?

14/9 inches, or an inch and 5/9 of an inch.

Step-by-step explanation:

If 2/3 inch is the same as 9 miles, then x inches represents 21 miles. We can then set up a proportion.

9 * x = (2/3) * 21

9x = 2 * 7

9x = 14

x = 14/9 inches.
