2.1.1.1.1. When the fraction is displayed as a mixed number, it is in proper form

3. Equivalent Fractions

3.1. Find the lowest common denominator (LCD) of the fractions to perform operations easier

4. Addition&Subtraction

4.1. Find the lowest common multiple (LCM) of the fractions to ensure equivalent fractions

4.1.1. Then add or subtract the numerators, while keeping the same denominator for your final answer

5. Multiplication

5.1. When multiplying fractions by whole numbers, write whole numbers over 1

5.2. When multiplying 2 fractions; multiply both the numerators and denominators

6. Division

6.1. Cross multiply
