Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.
You have to convert them to equivalent similar fractions (fractions with the same denominator) first.
Similar fractions occurs when the denominator or the bottom numbers are the same. In this case, adding similar fractions requires you to add the numerators; the top numbers together, and to keep the denominator the same. An example would be to add 2/8 and 5/8 equals 7/8.
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.
There isn't a universal answer to all problems. What you should try to do is find the lowest common denominator between the fractions you are adding.
you take away one of the whole number=then you add or subtract your fractions=
What is the answer for 8 1/3 - 5 2/6
Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.
We look at the signs of numbers when we need to combine them. We subtract only if numbers have different signs, otherwise we add them. So that, if we have in an expression several positive and negative numbers, we prefer to group numbers with the same sign and add them in order to subtract just once. While with fractions we like to group fractions with the same denominator first, and after that we can combine all fractions by finding their LCD.

If Bill says that he can add 23 and 40 without regrouping he is correct. Both numbers can easily be added in your head.

Finding the LCM will make adding and subtracting fractions easier.
Two fractions are similar if they have the same denominator.So if p/r and q/r are two such fractions, then p/r + q/r = (p+q)/r.
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.
