The cost of photographic paper is nearly proportional to the area of the paper. You own a painting whose dimensions are 24 inches by 30 inches. You create a small photographic reproduction whose smaller side is 5 inches. What is the scaling factor for this reproduction?
A) 0.2083
B) 0.1667
C) 0.0434
D) 0.0278

The scaling factor is the ratio of the smaller side of the reproduction to the smaller side of the original painting. In this case, the smaller side of the reproduction is 5 inches and the smaller side of the original painting is 24 inches, so the scaling factor is 5/24 = 0.2083.
