Problem Analysis

To solve this problem, we need to determine the number of guests at Kati's birthday party based on the information provided. Kati's mother baked two cakes, each divided into four parts. Then, each of these parts was divided into three smaller pieces. One piece was eaten by Kati, and two pieces were left. We need to find the number of guests at the party.

Solution

Let's break down the information step by step to find the solution:

1. Kati's mother baked two cakes. 2. Each cake was divided into four parts. 3. Each part was further divided into three smaller pieces. 4. One piece was eaten by Kati. 5. Two pieces were left.

To find the number of guests at the party, we need to determine the total number of pieces before Kati ate one. We can then subtract the two remaining pieces to find the number of guests.

Let's calculate the number of pieces before Kati ate one:

- Each cake was divided into four parts, so we have 2 cakes * 4 parts = 8 parts. - Each part was further divided into three smaller pieces, so we have 8 parts * 3 pieces = 24 pieces.

Now, let's subtract the two remaining pieces to find the number of guests:

- 24 pieces - 2 remaining pieces = 22 pieces.

Therefore, there were 22 guests at Kati's birthday party.

Answer

There were 22 guests at Kati's birthday party.
