First you need to fined what numbers you need to use.

next you need to do 21*3=63

(if you need) divide 3:63=21

so that is how you know if its right

Dixie Vincent · Answer 2

So Chris would have 1x, David would have 2x, and George would have 4x, so add them together and get 7x, so you divide by 7 and that's 3=x so Chris would have 3, David would have 6, and George would have 12
