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).

To do this, first we convert to twenty-eights. That gives us eight twenty-eights minus seven twenty-eights which equals one twenty-eight.
Nine sevenths, or one and two sevenths.
Equivalent fractions for two ninths are, four eighteenths or six twenty sevenths. Hope I helped.
