A "common denominator"

That's a common denominator.

Common denominator

That means that two or more fractions have the SAME denominator.

First, change it so that the two fractions have the same denominator (by changing the fractions into equivalent fractions). Once the two fractions have the same denominator, it is simply a case of subtracting the numerators, leaving the denominator the same. Finally, reduce the fraction to its lowest terms (if possible).

First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.

When adding two or more unlike fractions, yes.

There are an infinite number of correct answers.The two fractions areany number/any denominatorandthe same denominator minus the first number/the same denominator

Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.

Nothing actually happens. You are now in a position where the fractions may be added or subtracted more easily but that is all.

Subtract as if there were no denominators.

This is when two or more fractions have the same denominator (the number on the bottom). You can find a common denominator by trying different multiples of the fractions. I'm also aware that it's the name of a song by Justin Bieber on his new album! :D

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.

numerators you add, denominators you leave it the same

They have the same denominators.

They are in the same order, by size, as their numerators.

There has to be a set of two or more fractions for a lowest common denominator.

the least common denominator

If you mean the steps, they are as follows:* Identify a common denominator. Any common denominator will do. * Convert both fractions to equivalent fractions, with the common denominator found in the previous step. (If the fractions start off with the same denominator, there is nothing else to do in these first two steps.) * Add the numerators. That's the numerator of the result. Copy the common denominator as the denominator of the result. * Check whether you can simplify the resulting fraction.

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

convert the fractions so the denominators are the same if they aren't already. then add the numerators, but keep the denominator the same.

If the fractions have different denominators, you need to: 1) Convert to equivalent fractions with a common denominator, 2) Compare the numerators. If the fractions already have the same denominator, there is no need for the first step - which happens to be the most difficult step. Note that as a shortcut, you don't need the LEAST common denominator, any denominator can do. Thus, you can just use the product of the two denominators as the common denominator. As a result, to compare the fractions, you simply multiply the numerator of each fraction by the denominator of the other one, and then compare. However, this is still more work than simply comparing two numbers.
