The document provides steps for adding, subtracting, and simplifying fractions: 1. Find the least common denominator (LCD) to rewrite fractions with different denominators as equivalent fractions with a common denominator. 2. Add or subtract the numerators of the equivalent fractions and keep the common denominator. 3. Simplify the resulting fraction if possible by dividing the numerator and denominator by their greatest common factor.

2. Steps:
1. Cross multiply the wings.
2. Add the products to find the
numerator.
3. Multiply the denominators of the
fractions to find the denominator.
4. Simplify if needed.
