<h3>How to determine the better method?</h3>
From the question, we understand the Collin selected random names from the school directory.
While Karl surveyed only the students sitting close to him.
Karl's method is biased because students sitting far from him do not have a chance of being surveyed.
Hence, Collin's sampling method will better represent the entire population.

Answer:
18
Step-by-step explanation:
Let x represent smallest number and y represent second number.
We have been given that the biggest among three numbers is 2.4 larger than the smallest one. So biggest number would be
.
We are also told that 15 times the smallest one is equal to 12 times the second and 10 times the third. We can represent this information in equations as:


Upon solving 2nd equation, we will get:





Therefore, the smallest number is 4.8.
The biggest number would be
.
Upon substituting
in equation (1), we will get:




Therefore, 2nd number would be 6.
Let us find sum of all numbers as:

Therefore, the sum of all 3 numbers would be 18.
