When Adding Fractions Do You Add The Denominator
Camila Farah
After you convert the fractions so that they have common denominators you just add the numerators.
If you didn t already know when we re adding and subtracting fractions they must be homogeneous. The lowest common denominator of two or more numbers is the smallest whole number that is divisible by each. Make sure the bottom numbers the denominators are the same step 2. Now that you have the same denominators you can add the numerators straight across.
If not multiply each fraction by the other fraction s denominator to give them a common denominator. So our lcd 6. Now you can add these together. This fraction can t be reduced further so 37 40 is the final answer.
Adding fractions is easy when the denominators the numbers below the line are the same. Because the numerator and the denominator are both even numbers you know that the fraction can be reduced. It s really just the lcm of our denominators 2 and 3. When the denominators are the same you are adding fractions that have the same amount of equal parts.

Add the numerators put that answer over the denominator step 3. The main rule of this game is that we can t do anything until the denominators are the same. This is a bit tricky but you ll think it s easy once you get used to it. Simplify the fraction if needed.
To add fractions start by checking the denominator of each fraction to make sure it s the same number. The fraction calculator can add or subtract 2 fractions 3 fractions and up to 9 fractions at a time and shows the work to find common denominators and simplify fractions to lowest terms or mixed number answers. A common multiple of 2 and 3 is 6. If you set up an algebraic equation to add fractions with different denominators you need to find the lowest common denominator first.
Add the numerators but leave the denominators alone. Again remember that everything you do to the denominator needs to be done to the numerator as well so multiply the top and bottom by 6 to get 6 12. So for each fraction we need an equivalent fraction with a denominator of 6. In this case that will mean that 6 12 1 12 7 12.
