Final answer:
To make 25 hotcakes, Zeny will need to use a simple proportion based on the recipe's ratio of 3 eggs for 5 hotcakes, which results in a total of 15 eggs needed for 25 hotcakes.
Step-by-step explanation:
The question is about determining the number of eggs needed to make a specific quantity of hotcakes based on a given ratio. Given that Zeny wants to make 25 hotcakes and the recipe calls for 3 eggs to make 5 hotcakes, we need to find out how many times the original recipe will be multiplied to make 25 hotcakes. We'll use a simple proportion to solve this.
To determine the number of eggs needed, we set up a ratio using the information provided:
(3 eggs / 5 hotcakes) = (x eggs / 25 hotcakes)
Solving for x, we find that:
So, Zeny will need 15 eggs to make 25 hotcakes.
