When the denominators are not the same, you need to multiply both top and bottom of the fractions until the denominators are the same. For instance, if we wanted to do 1/3 + 2/9, we would need to first multiply top and bottom of the first fraction by 3, which makes the question 3/9 + 2/9. Once the denominators are the same, the subtraction or addition can be completed as outlined in the first paragraph
