    3 ^_^ if you multiply the first one by 3 , then you'll get the same denominator.

    because we already have 9 in the denominator

    we want 2/3 to have the same denominator as 4/9 so we multiply 2/3 with 3 both parts :)

    so when we do, we get 6/9 and 4/9, both have the same denominator we stop :)

    we want both to have the same denominator, what can we do? hmmm we know that 3x3 = 9 so we multiply both parts of 2/3 with 3
