Explore the 3 easy steps to adding fractions.

Step 1 - Common Denominators

Jan 1, 1901

You have to make sure the bottom numbers (denominators) are the same. If they are different, fix them by multiplying the top and bottom of the small fraction to make the denominator match the large fraction. In this example, 1/3 would be multiplied by 2/2 to turn into 2/6.

Step 1 Solution

Jun 30, 1901

As you can see, 1/3 became 1/6. You should re-write your problem like this.

Step 2 - Adding the Numerators

Jan 1, 1902

Add the numerators (top numbers) straight across. Put the answer at the top of your answer fraction.

Step 2 Solution

Jun 30, 1902

You will keep the denominator (bottom number) the same. Your answer fraction should look like this.

Step 3 - Finding the Greatest Common Factor

Jan 1, 1903

Now you have to reduce the fraction if needed. Find the greatest common factor of both the numerator and denominator.

Step 3 Solution

Jun 30, 1903

The greatest common factor of 3 & 6 is 3. If you divide 3 by 3 the answer is 1. If you divide 6 by 3 the answer is 2. Your new answer fraction is 1/2.
