You firstly find the lowest common denominator (bottom number of the fraction) and convert the fractions to this, e.g. 1/3 + 1/6 = 2/6 + 1/6 The next step is to simply add the numerators (top number of the fraction: e.g. 2/6 + 1/6 = 3/6 Finally you should tidy the fraction up by reducing it to its lowest form by dividing the denominator and numerators by the same number e.g. divide by 3 - 3/6 = 1/2

Why do you need a common 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.
How do you find the sum of two mixed numbers?
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.
When you add two fractions the answer is called?
the sum the sum
What is the halfway between fractions?
Halfway between two fractions would be the average of the two fractions, so add the two fractions together and divide by two! Let's take 1/2 and 3/4 as an example. Add 1/2 (or 2/4) and 3/4 and you get 5/4. Now divide by two ( or multiply the bottom part by two) and your answer is 5/8!
How do you find the mean of two fractions?
Add them together, then divide by 2.
What are compatible numbers for fractions?
I am not entirely sure what you mean, but if you need to add, subtract, or compare two fractions, they need to have the same denominator.
How do you add two fractions that have like denominators?
In fractions, you can NEVER add or subtract

Why do fractions need a common denominator when adding subtracting?
In order to add or subtract one fraction from another, they must have a common denominator, or the same denominator. That's because it's impossible to add two fractions that have a different number of parts.
When you add two fractions together the answer is called a?
An answer.
How is adding like fractions and adding unlike fractions the same?
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.
How do you find the sum of two mixed numbers?
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.
Why are two fractions converted into like fractions?
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.
Adding unlike fractions?
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.
Do you need to get the LCM of mixed numbers?
Only to add, subtract, or compare two fractions. Note: Technically, to add two fractions (for example) you don't need the LEAST common multiple; any common multiple will do. As an example, if you want to add 1/4 + 1/6 (or any mixed number that ends with this fraction), you can use 24 as a common denominator (you can obtain this by multiplying 4 x 6), even though the least common multiple is 12.To add two mixed fractions, the easiest way is usually to add the whole part and the fractional part separately.
How do you add two fractions with a different denominator?
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.
How do you add two fractions with the same denominator?
numerators you add, denominators you leave it the same
