Question

If you have 18 students and all are paired up at least once how many projects in the year

Answer 1

9. A pair is two. 18 divided by two is 9.

Answer 2

It would be 9 because you get half the number of projects because 18 students are partners and if you divide that you would have 9 groups of 2 and if you multiply that by the number of projects you would get the number of projects (ex:18 dividend by 2 it's 9 then if there is three projects assigned you multiply 9 by 3 to get 27 projects got it?
