Multiplying with 6 is like multiplying with 3 because, you just double it. Let's say 3 × 4 = 12
Its the same as 6 × 2 = 12 ... which is just 3 + 3 + 3 + 3 . ((:

It has a common multiple.so pretty much *ALMOST* anything you multiply with either of them you can do for the other one

3 x 10=30
~ GOOD
6 x 5=30

3 x 7= 21
~ BAD
6 x 3=18
