Question

how many nurses will take charge of 20 patients if 6 handles 35 patients?​

Answer 1

Considering we can't have half person, it'll take 4 nurses to handle 20 patients.

The math behind it is not that hard. First, we'll focus on finding out how many patients one nurse is able to deal with. In order to do that, observe the calculation bellow:

If 6 nurses handle 35 patients

  X nurses habdle 20 patients

This will lead us to the following situation:

35X = 120 = 3,4.

As previously stated, we can't have half person, which leads us to the next rounded number, which is 4.
