Answer:
1/3 + 2/7 = 13/21
Step-by-step explanation:
When we add two fractions, such as 1/3 + 2/7, we make sure that the two denominators are the same and then we simply add the numerators.
In cases where the denominators are not the same, we find the lowest common denominator and adjust the fractions to keep them intact.
We also simplify the answers to fraction problems whenever possible.
