    solve for m and n ?

    1 , 3, 9, 12 ,16

    m and n are two different numbers from the list. m is a factor of 12 and  m = 4n

    Find m and n

    i don't really understand how to do this question because if m is a factor of 12 than m could either equal 3 or 12. how are you suppose to know which one to choose?

    can someone please go through it step by step for me ? thank you

    Looks like you would choose m = 12 and n = 3, since m = 4n means that 12 = 4(3)
