# How to Add Three Fractions Altogether (Three Fractions)

Learn how to add three fractions altogether.

Adding 3 fractions can be done in the following way:

**Step 1** First find the common denominator of your 3 fractions. Decide which number all the denominator divide into without a remainder (this is also known as the lowest common multiply)

**Step 2** Make equivalent fractions have the denominator worked out in step 1.

**Step 3** Add the 3 fractions altogether. Simplify your final answer if necessary or change the fraction to a mixed number if the questions states this.

**Example 1 **

Add together these 3 fractions:

1/2 + 3/5 + 1/10

**Step 1**

The common denominator is 10 as 2, 5 and 10 all divide into 10.

**Step 2**

The equivalent fractions are:

½ = 5/10

3/5 = 6/10

1/10 = 1/10 (unchanged)

**Step 3**

5/10 + 6/10 + 1/10 = 12/10 = 6/5

**Example 2 **

Add together these 3 fractions:

2/5 + 1/3 + 3/10

**Step 1**

The common denominator is 30 as 5, 3 and 10 all divide into 30.

**Step 2**

The equivalent fractions are:

2/5 = 12/30

1/3 = 10/30

3/10 = 9/30 (unchanged)

**Step 3**

12/30 + 10/30 + 9/30 = 31/30 (or 1 1/30 if you prefer mixed numbers)
