Understand the idea
The denominator tells you the size of each part. When denominators match, add the numerators and keep the denominator.
See a worked example
2/7 + 3/7 = 5/7. Two sevenths plus three sevenths gives five sevenths.
A useful check
Do not add the denominators when the parts are already the same size.
