Subtracting mixed numbers
Subtracting mixed numbers is a bit more difficult than adding. Watch the video below for instructions.
Adding mixed numbers
When adding mixed numbers, we can start by adding the whole numbers, then adding the fractions. For example:
1 1/4 + 2 1/4
This means the same as 1 + 1/4 + 2 + 1/4
So I can start by adding my whole numbers, 1 + 2 = 3
Then add my fractions, 1/4 + 1/4 = 2/4
2/4 can be simplified to 1/2
So I end up with 3 1/2
The same thing happens if I add numbers with unlike denominators. For example:
1 1/4 + 2 1/3
This is the same as 1 + 1/4 + 2 + 1/3
I can start by adding my whole numbers: 1 + 2 = 3
Then add my fractions: 1/4 + 1/3
This time I need to find my lowest common denominator between 3 and 4. The lowest common denominator is 12, so I end up with:
3/12 + 4/12 = 7/12
Then I add my whole number back in to get:
3 7/12
