If on a scale drawing 240 feet are represented by 10 inches,
then a scale of ¼ inch
represents how many feet?

6 feet

Step-by-step explanation:

240 feet : 10 inches

24 feet    : 1 inch

? feet       : 1/4 inch

to get from 1 to a 1/4 you divide by 4, so you do 24 ÷ 4

24 ÷ 4 = 6

6 ft

Step-by-step explanation:

First, make this visually understandable using a ratio:

240 ft = x ft

10 in     in

To find the change between the inches,

1/4 ÷ 10 = 0.025

Use this same amount to find x ft:

240 (0.025) = 6

x = 6 ft

To double-check:

240/10 = 24

6/0.25 = 24
