Answer 1

answer: it is asking for you to calculate

Answer 2

It is asking you to "calculate/solve" that (something not included in your question), followed by rounding the result sensibly. An example of a "sensible" rounding could be "average of 30.85 students per teacher" -> "31 students per teacher."
