The rotation of the gears in he mesh involves a circular motion
The second gear has 2 teeth
<h3>How to determine the number of teeth?</h3>
The given parameter can be represented using the following ratio:
Ratio = Teeth : Revolution
So, we have:
23 : 60 = Teeth : 5
Express as fraction
23/60 = Teeth/5
Multiply both sides by 5
Teeth = 5*23/60
Evaluate the product
Teeth = 2
Hence, the second gear has 2 teeth

The student should have phrased it to be "the difference between the product of 5 and y and 15", as the way the student writes it implies that 5y is being subtracted from 15 instead of the other way around.
