How do you add improper fractions and regular fractions?

To add improper fractions and regular fractions, first convert any mixed numbers into improper fractions if necessary. Ensure both fractions have a common denominator; if they don’t, find the least common denominator (LCD) and convert each fraction accordingly. Once you have the same denominator, add the numerators together while keeping the denominator the same. Finally, simplify the resulting fraction if possible.
