Adding Fraction Powerpoint Presentation

1. ADDING FRACTION

2. To add fractions there are Three Simple Steps:
•Step 1: AMake 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 needed)

4. 1.MAKING THE DENOMINATORS
THE SAME

5. Finding the Least Common Denominator
•Common Denominator?
When the denominators of two or more fractions are
the same, they have Common Denominators.
•Least Common Denominator?
•it is the smallest of all the common denominators.
•Why do we need common denominators?
•Because we can't add fractions with different
denominators:

6. Least Common Denominator
Before we can add them we must make the denominators the same.

7. Multiply the current denominators together:
3 × 6 = 18

20. Adding Mixed Fractions

21. Adding Mixed Fractions
•convert them to Improper Fractions
•then add them (using Addition of
Fractions)
•then convert back to Mixed
Fractions
