Question

pencils come in packages of 10. erasers come in packages of 12. Philip wants to purchase the small est number of pencils and erasers so that he will have exactly 1 eraser per pencil. how many packages of pencils and erasers should Philip buy ?

Answer 1

10 = 2*5
12 = 2*6
LCM(10,12) = 2*5*6 = 60
You will need 60 of each item.
This gets you the solution posted above

Answer 2

This question makes no sense. It's part of my sons homework. He doesn't say how many pencils he wants, just that he wants an eraser for each. So if you go off the what the question says, it should be one packages of each.
