Compute the sum: 4 2/7 plus 3 5/7.

Explanation:
When adding mixed numbers with the same denominator, you can add the whole parts and the fractions separately. Here, 4 plus 3 gives 7. The fractions 2/7 and 5/7 add to 7/7, which equals 1. So you have 7 plus that 1, totaling 8. (You can also see this by converting to improper fractions: 4 2/7 = 30/7 and 3 5/7 = 26/7, and 30/7 + 26/7 = 56/7 = 8.)
