1) Adding fractions with like denominators is simple - just add the numerators. 2) Adding fractions with unlike denominators requires finding a common denominator first before adding the numerators. 3) Subtracting fractions follows the same process as adding, but substituting subtraction for addition in the appropriate steps.

- 1. Adding & Subtracting Fractions Dakota L. 8-41
- 2. Adding like Denominators To add like denominators is the easiest part about fractions there is: now all you have to do is add the numerator!
- 3. Adding Like Denominators II That one was easy so I’m sure that you knew the answer already:
- 4. Adding un-like Denominators Now, this procedure is a bit more challenging then adding like denominators! This time you must find the common denominator before u can do any adding! now we must find a common denominator! what you do to the “D” you must do to the “N”. 1. now we must convert the answer to a mixed fraction because the “N” is greater then the “D”. 2.
- 5. Subtracting Like Denominators This procedure is just like the adding like denominators…except…were subtracting! Now we just have to subtract the Numerators! Think were done? We still have to Reduce!
- 6. Subtracting Un-Like Denominators Same procedure as adding un-like “D’s”…except…we’re subtracting! Now we must find the common denominator!
