ADDITION: Example 2

**Rule 18:**
- To add fractions, the denominators must be equal.
Complete the following steps to add two fractions.
**1.**
- Build each fraction so that both denominators are equal.
**2.**
- Add the numerators of the fractions.
**3.**
- The denominators will be the denominator of the built-up fractions.
**4.**
- Reduce the answer.

**Example:**
- Calculate .
**Answer:**
- The answer is .
**Solution:**
- The denominators are different, so you must build each fraction to a form where they both have the same denominator. Since both 4 and 6 will divide evenly into 12, build both fractions to a denominator of 12.
and
.

can now be written .
Add the numerators for the numerator in the answer. 9 + 2
= 11.

The answer is .

This answer is already reduced, so you can skip step 4.

**Check:**
- You can check the answer with your calculator. Calculate 3 divided by 4, 1 divided by 6, and add the results. Now divide 11 by 12. Both answers should be the same.
