What rules have you applied in adding and subtracting fractions?
To add or subtract fractions they must have the same denominator (the bottom value). If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value). If the denominators are different then a common denominator needs to be found.
How do you add three fractions with different denominators?
Addition of 3 fractions with different denominators Steps to add fractions with different denominators are: Step 1: Find LCM of denominators. Step 2: Divide the LCM by the denominator of each number which are to be added. Step 3: Multiply the numerator with the quotient ( found in the above step).
What are the rules for adding fractions?
To add fractions there are Three Simple Steps:
- Step 1: Make sure the bottom numbers (the denominators) are the same.
- Step 2: Add the top numbers (the numerators), put that answer over the denominator.
- Step 3: Simplify the fraction (if possible)
What are the steps in adding mixed numbers with dissimilar fractions?
Step 1: Keep the denominator the same. Step 2: Add or subtract the numerators. Step 3: If the answer is an improper form, reduce the fraction into a mixed number. Exercise 1: Add the fractions, + .

What are the rules for improper fractions?
FRACTION RULES Multiplying and Dividing Fractions: 1. Common denominators are NOT needed. 2. Always change mixed numbers to improper fractions. 3. CANCEL (reduce) between any numerator and any denominator if you can, but cancel only when a multiplication sign is present: Never cancel when you have a division sign. 4.
