A model doll house is 3.25 feet long. The real house is 30 yards long. What is the unit rate that describes the relationship of the real house to the model doll house?

A. 9.23yards/foot

B. 3.25feet/30yards

C. 30yards/foot

D. 3.25feet/yard

If you would like to know the unit rate that describes the relationship of the real house to the model doll house, you can calculate this using the following steps:

3.25 feet ... 30 yards

1 foot ... x yards = ?

3.25 * x = 30 * 1

3.25 * x = 30

x = 30 / 3.25

x = 9.23 yards

The correct result would be 9.23 yards/foot.
