If the fractions have the same denominator, you can add and subtract them by adding or subtracting the numerator. For instance 2/7 + 3/7 = 5/7
Or 7/9 - 2/9 = 5/9
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.

What is the meaning of addition and subtraction of similar fraction?
Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.
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.

What are the rules of the dissimilar fractions?
I assume you mean, with different denominators. If you want to add the fractions, subtract them, or compare them (determine which one is greater), you have to convert them to similar fractions (fractions with the same denominator) first. Converting to similar fractions is not necessary, and usually doesn't even help, if you want to multiply or divide fractions.
