Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.

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.

When you want to add fractions that have different denominators, you have to convert them into fractions that do have the same denominators. So for example, how much is a half plus a third? Both of these can be converted into sixths, so one half equals three sixths, and one third equals two sixths. Three sixths plus two sixths equals five sixths. That's the answer. If you have three fractions with different denominators, the procedure is the same. Convert all three into fractions with the same denominators, then add them.

numerators you add, denominators you leave it the same

SUBTRACTION: You first turn both mixed numbers into improper fractions. If needed, change the denominators into like denominators. Next, subtract the two improper fractions and reduce if necessary. ADDITION: If needed, turn denominators so they are the same number. Next, add and reduce if necessary.

You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.

When adding unlike fractions, find the LCM of the denominators and convert them to it.

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.

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

When adding unlike fractions, find the LCM of the denominators and convert them to it.

To find the sum of two mixed numbers, turn the mixed numbers into improper fractions (multiply the base with the denominator and add the numerator), then add the two fractions. To add the two fractions, find the LCD (lowest common denominator) and add the two numerators, but leave the denominators the same.

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

No, the LCM of the denominators.

Multiplying the denominators together of two or more unlike fractions will get you a common multiple.

you make them have like denominators by multiplying so many times that they have the same denominators or you can make them have like denominators by multiplying the two

STEP ONE: Get a common denominator. STEP TWO: Add or subtract the numerators. STEP THREE: Simplify the result if needed. Notice that 3/27 can be simplified, since the numerator and denominator are both divisible by 3. And that's all there is to it! Final Answer:

The least common denominator of two fractions is the least common multiple of the two denominators.

The first step, to add, subtract, or compare fractions, is always to convert the fractions to equivalent fractions, that all have the same denominator. You can use one of several techniques to get the LEAST common denominator, or simply multiply the two denominators to get a common denominator (which in this case may, or may not, be the smallest common denominator).

The LCD of two fractions is the same as the LCM of their denominators.

If the denominators (bottom numbers) are not equal, making equivalent fractions of them so that the denominators are equal. With the denominators equal if the numerators (top numbers) are equal, then the fractions are equal.
