-When adding fractions first need to have a common denominator.
-You can get the common denominator by listing some multiples and seeing which one they have in common. Or you can multiply the denominators together.
-When subtracting fractions you do the same thing wih the adding but after you find the common denominator you subtract.
-There are a few ways you can divide fractions. The first is by using a ratio table.
- I will also show you how to solve it using a reciprocal. It is the inverse of the denominator.
