Question

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

Answer 1

1 5/9 ich represent 21 miles

Explanation:

Proportions:

2/3 inch ⇔ 9 miles

M inch ⇔ 21 miles

M = 21*(2/3) / 9

M = 14/9

14/9 = 9/9 + 5/9 = 1 + 5/9 = 1 5/9 inch

Answer 2

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

Explanation:

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

`((2)/(3) )/(9) =(x)/(21)`

9 * x = (2/3) * 21

9x = 2 * 7

9x = 14

x = 14/9 inches.

Hope this helps!
