UNIT 6: FRACTION ADDITION - DIFFERENT DENOMINATORS (PART 1)

To add fractions with different denominators, you must first change both denominators to be the same. EXAMPLES:


To do this you will need the skills you learned in Unit 5. Once you have both denominators the same, then you just add the numerators. If the denominator of one fraction divides evenly (no remainder) into the other, then change the fraction with the smaller denominator to a fraction with the larger denominator, then add numerators. The denominator will be the LARGER of the 2 denominators.

Add these fractions: (I will give you the first 3 common denominators!)
