Case 1: Adding and Subtracting Improper Fractions with Common Denominators Step 1: Keep the denominator the same Step 2: Add or subtract the numerators
Adding Fractions: If the denominators are not the same, you must find the common denominator by finding the least common multiple (LCM) Example: 3 7 + 1
When you add or subtract fractions, you begin by finding a common denominator To Add or Subtract Two Rational Expressions with Unlike Denominators
Basic Arithmetic Skill Adding or Subtracting Fractions with Different Denominators Evaluate each expression 1) 3 4 + 2 5 2) 1 + 9 5 3) 13 7 + 3 2 4) 5 8
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, +
So to add 'like' fractions we just add the numerators The process is similar for subtraction, but we take away instead of adding Example Calculate 5 8
