Calculation of the Number of Pies Prepared

To calculate the number of pies that were prepared by your grandmother, we can use the information provided.

According to the information given, 15 pies were eaten for breakfast, and a quarter of the pies remained after breakfast.

To find the total number of pies, we can use the following equation:

Total number of pies = Number of pies eaten + Number of pies remaining

Let's substitute the values into the equation:

Total number of pies = 15 + (1/4) * Total number of pies

To solve this equation, we can multiply both sides by 4 to eliminate the fraction:

4 * Total number of pies = 60 + Total number of pies

Simplifying the equation:

3 * Total number of pies = 60

Finally, we can solve for the total number of pies:

Total number of pies = 60 / 3 = 20

Therefore, your grandmother prepared 20 pies for breakfast.
