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
Similar fractions are those denominators the same.
it stay the same when you subtract fractions and when you add fractions.
As a review, similar fractions (also like fractions) are fractions having the same denominators
You can compare similar fractions by looking at their numerators. You can compare dissimilar fractions by converting them to similar fractions and looking at their numerators. You can convert a dissimilar fraction to a similar fraction by finding the least common denominator.
You need a common denominator in order to add or subtract fractions.
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.
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.
to change dessimilar fractions to similar fractions you divide
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.
You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.
Similar fractions are those denominators the same.
it stay the same when you subtract fractions and when you add fractions.
Adding like terms can be like adding fractions. You can only add fractions with a common denomonator. You can only combine terms together if they are like. Think of like terms as denomonators. You can only add if they are like.
