Final answer:
To find the fraction of the total number of hats that was left over, subtract the number of hats sold from the total number of hats.
Step-by-step explanation:
To find the fraction of the total number of hats that was left over, we need to subtract the number of hats sold from the total number of hats. Let's say the total number of hats was x.
On Saturday, Salvador sold 47 hats, so there were x - 47 hats left.
On Sunday, he sold 14 hats, so there were (x - 47) - 14 = x - 61 hats left.
The fraction of hats left over is (x - 61) / x.
