The document discusses adding and subtracting fractions with like denominators. It explains that fractions have like denominators if they have the same number on the bottom. To add fractions with like denominators, you add the top numbers and keep the bottom number the same. To subtract fractions with like denominators, you follow the same steps as addition but subtract the top numbers instead of adding them. Examples are provided to demonstrate both addition and subtraction of fractions with like denominators.

2. Quick Review Denominator – the number at the bottom of the fraction. This number names the total number of parts that equals a whole Like denominators This means that the denominators are the same (equal) Example: Look at the fractions below 3 4 1 4 Both fractions have the same denominator – called like denominators and

3. Add Fractions with Like Denominators Step 1 : Add the numerators. This sum becomes the numerator in your answer. 3 4 + 1 4 = 4

4. Step 2: Keep the same denominator that is in the problem. 3 4 + 1 4 = 4 4

5. Step 3: Simplify (reduce to the lowest terms) your answer 4 4 = 1 Remember that in order to find the simplest form, you must find the greatest common factor of the numerator and the denominator. GCF = 4 ÷ ÷ 4 4

6. Add Fractions with Like Denominators Step 1 : Add the numerators. This sum becomes the numerator in your answer. 2 6 + 2 6 = 4

7. Step 2: Keep the same denominator that is in the problem. 2 6 + 2 6 = 4 6

8. Step 3: Simplify (reduce to the lowest terms) your answer 4 6 Remember that in order to find the simplest form, you must find the greatest common factor of the numerator and the denominator. GCF = 2 ÷ ÷ 2 2 = 2 3

9. You try it! 5 10 + 3 10 = 13 22 + 3 22 =

10. Subtract Fractions with Like Denominators To subtract fractions with like denominators, you follow the SAME steps as you did for addition, except you have to subtract!

11. Step 1: Subtract the numerators. This sum becomes the numerator in your answer. 3 4 - 1 4 = 2

12. Step 2: Keep the same denominator that is in the problem. 3 4 - 1 4 = 2 4

13. Step 3: Simplify (reduce to the lowest terms) your answer Remember that in order to find the simplest form, you must find the greatest common factor of the numerator and the denominator. GCF = 2 2 4 ÷ ÷ 2 2 = 1 2

14. Step 1: Subtract the numerators. This sum becomes the numerator in your answer. 13 6 - 9 6 = 4

15. Step 2: Keep the same denominator that is in the problem. 13 6 - 9 6 = 4 6

16. Step 3: Simplify (reduce to the lowest terms) your answer Remember that in order to find the simplest form, you must find the greatest common factor of the numerator and the denominator. GCF = 2 4 6 ÷ ÷ 2 2 = 2 3

17. Your turn! 11 10 - 7 10 = 13 22 - 3 22 =
