The process of adding fractions entails merging fractions that either have identical or different denominators. If the denominators are identical, you can proceed to add the numerators. However, if they're different, you'll need to ascertain a common denominator by multiplying the two denominators. Following this, you'll need to adjust the numerators before you add them. Don't forget to simplify the final fraction if needed.
