Question

If `1/4` inch represents 5 yards, how many inches long must a scale drawing be to show a football field 100 yards long?

Answer 1

`x= 25 " "`inches

Explanation:

Using the proportion method of comparing scales and distances means that you do not have to spend time converting between the units.
Let `x` be the distance in inches

`"inches"/" yards" " "0.25/5 = x/100`

`x = (0.25 xx100)/5`

`x= 5 " "`inches
