Answer :

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

ratio = 25:5 (students:teachers)

teachers = 155

students = ?

Step 02:

[tex]\begin{gathered} \text{students = 155 teachers }\cdot\text{ }\frac{25\text{ students }}{5\text{ teachers}} \\ \text{students = }775\text{ } \end{gathered}[/tex]

Carlos is correct.

[tex]\frac{25}{5}=\frac{x}{155}[/tex]

The answer is:

There are 775 students.

Carlos is correct.

Mike set the variables to find in the wrong way.
