Calculating the Number of Eggs Used for the Salad

To calculate the number of eggs used for the salad, we can use the information provided.

Given: - The grandmother used 2/9 of the eggs for the pies. - The remaining eggs were used for the salad. - The total number of eggs used for the pies is 8.

Let's calculate the number of eggs used for the salad.

First, we need to find the total number of eggs the grandmother had.

Total number of eggs = Eggs used for pies / (2/9) = 8 / (2/9)

Using the formula for dividing by a fraction: Total number of eggs = 8 / (2/9) = 8 * (9/2) = 36

Now, we can find the number of eggs used for the salad.

Eggs used for salad = Total number of eggs - Eggs used for pies = 36 - 8 = 28

So, the grandmother used 28 eggs for the salad.
