School guidelines require that there must be at least 2 chaperones for every 25 students going on a school trip. how many chaperones must there be for 53 students?
2 chaperones
27 chaperones
4 chaperones
5 chaperones

We can use ratio and proportion to find the number of chaperones

Let represent the number of chaperones.

Number of Students                                    Number of Chaperones

25                                                                                   2

53                                                                                

If 25 corresponds to 2, then 53 will correspond to a value more than 2. If more, less divides, hence

Since humans are whole entities, we round up to the nearest whole number which is 5.

The point is that we are dealing with humans and 4.24 means 4 chaperones plus 0.24 chaperone. since we cannot add 0.24 of the next chaperone to the 4, we add one full chaperone.
