Final answer:
To find the three natural numbers given the product of the first two numbers and the product of the last two numbers, as well as the sum of the first and third numbers, we can set up equations and solve. However, in this case, there is no solution for the problem.
Step-by-step explanation:
To find the three natural numbers, let's call them a, b, and c. We're given that the product of the first two numbers is 54, so we can write that as:
a * b = 54
The product of the last two numbers is 12, so we can write:
b * c = 12
The sum of the first and third numbers is 11, so we can write:
a + c = 11
From the first equation, we can see that a can either be 1 and b can be 54, or a can be 2 and b can be 27. However, in both cases, we don't get any natural number solutions for c. Therefore, there is no solution for this problem.
