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).
2/21
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
4 sevenths just over half
No.

yes
Nine sevenths, or one and two sevenths.
One seventh is larger than one eleventh, and thus four sevenths will be larger as well. Consider this: if you take two identical pizzas and cut one into 7 slices and other other in 11, the one cut into 7 will have the bigger slices.
Yes .__.
Two sevenths are closer to a half.
Five sevenths
one and five sevenths
