Final answer:
If 272 hot dogs were sold at the baseball stadium, 102 hamburgers were sold.
Step-by-step explanation:
To find the number of hamburgers sold, we need to use the ratio of hot dogs to hamburgers sold at the baseball stadium, which is 8:3.
If 272 hot dogs were sold, we can set up a proportion as follows:
8/3 = 272/x
To solve for x, we can cross multiply and solve for x:
8x = 816
x = 816/8
x = 102
Therefore, 102 hamburgers were sold at the baseball stadium.
