    The common denominator is 21. So 1/3 would become 7/21 and 2/7 would become 6/21.

    Okay let's say I have 1/2 and 2/4 (this is really easy) so you take the multiples of the denominator and the numbers that are the same are known as common denominators so its

    3 6 9 12 15 18 21 24

    7 14 21 28

    so that means 21 is the common denominator but there are way more than that trust me so now hopefully you guys get it
