Question

four hundred forty-two students were placed into 24 groups with about the same number of students in each group. Using compatible numbers, what is the best estimate of the number of students in each group?

Answer 1

First we have to divede the tota of students into the sice of each grop so:

$\frac{442}{24}=18.4$

So we can aproximate this to a whole number so:

$\frac{450}{25}=18$
