You multiply to make the denominators the same then add.
To add 12/13 and 15/7 you do the following:
- multiply 12/13 by 7/7 giving 84/91
- multiply 15/7 by 13/13 giving 195/91
- add 84/91 and 195/91 giving 279/91
- if possible try to remove common factors from numerator and denominator, but that isn't possible here.

How do you add the dissimilar fraction?
You have to convert them to equivalent similar fractions (fractions with the same denominator) first.
What are the instruction in adding dissimilar fraction?
You must first convert the fractions to a common denominator. Then just add the numerators (the top part of the fraction).
How do you add and subtract dissimilar fraction in simple and mixed formed?
In adding or subtracting dissimilar fractions, you will need first to get its LCD or least common denominator. For example: 3/2 + 5/3 = ? We will get the LCD of two and three and we will get 6 So the equation will become: 9/6 + 10/6 Then the final answer will be : 19/6
How can you add similar and dissimilar fractions?
Adding similar fractions is easy, but adding dissimilar ones requires an additional step. Before you begin, you must know a few important key terms. First, the number on the top of a fraction is called the numerator, while the number on the bottom of a fraction is called the denominator. Similar fractions have the same denominator, also called a common denominator. To add dissimilar fractions (fractions with different denominators), you must first convert the fractions so that the denominators are the same.
