Question

If on a scale drawing 100 feet are represented by 15 inches, then a scale of 1/2 inches represents how many feet

Answer 1

3 1/3 feet

Explanation:

100 feet : 15 inches

3 1/3 feet : 1/2 inch

Answer 2

`3(1)/(3)` feet

Explanation:

Inches : Feet = 15 : 100

Let 'x' be the feet required to find

15 : 100 :: 1/2 : x

Product of extremes = product of means

15 * x = 100 * (1/2)

15 * x = 50

x = 50/15

x = 10/3

x =
`3(1)/(3)`
