Oh, dude, let me break it down for you. So, one third is about 0.33, and two sevenths is around 0.29. Clearly, 0.33 is bigger than 0.29, so one third is larger than two sevenths. Math can be fun, right?

Well, firstly, the LCM (Lowest Common Multiple) of 3 and 7 is 21. Try to convert those fractions into fractions with denominators of 21. Multiply 3x7 in one thirds and 1x7, which changes one third to seven twenty-oneths. Multiply 7x3 in two sevenths and 2x3, which changes two sevenths to six twenty-oneths. Therefore, one third (seven twenty-oneths) is greater than two sevenths (six twenty-oneths).

Well, isn't that a happy little math problem we have here! To find one third of six sevenths, we can first simplify six sevenths to two thirds. Then, we can take one third of two thirds, which equals two ninths. Just remember, there are no mistakes in math, only happy little accidents!
Nine sevenths, or one and two sevenths.
Convert both to fifteenths (3x5). One third is 5/15 and two fifths is 6/15, so two fifths is larger.
The sum of 1/3 and 2/7 is 13/21
