Tim wants to model a dollhouse from a real house that measures 60 feet in length by 28 feet in width. he decides to use a scale in which 1/4 inch equals 1 foot. what will the dimensions of his model be?

length= inches
width= inches

There are two ways you can use to answer this question, I'll put both so you can decide which makes sense to you:
1. You could say that for every foot, you go 0.25 inches (because 0.25 is 1/4) and therefore if you do 0.25 × 60, you get the length as 15 inches, and 0.25 × 7, you get the width as 7 inches.
2. You could think of it a different way, and say that if 0.25 inches is 1 foot, then 1 inch must be 4 feet. Using this logic, you can then divide 60 by 4 to get 15, and divide 28 by 4 to get 7.

Either way you use, you get the length as 15 inches, and the width as 7 inches. Hope this helps!

Do the inverse operation
