Adding Fractions With Different Denominators

Adding Fractions With Different Denominators

When adding fractions that have different denominators you should find a common denominator by either multiplying or dividing, for example:

1/2 + 6/10 =

1/2 x 5 = 5/10 

5/10 + 6/10 = 11/10 

11/10 is an improper fraction so you must find how much groups of 10 is in 11, 1 so there would be 1/10 left, so the answer would be 1 1/10 

If the question has wholes with the fraction (a mixed number) you should do the following:

5 7/8 + 3 2/4 =

5 + 3 = 8 (these are the wholes)

2/4 x 2 = 4/8 

7/8 + 4/8 = 11/8(an improper fraction)

Do as before when you have an improper fraction so you get a mixed number. And add the wholes in the end.

1 3/8 + 8 = 9 3/8
