**Rule 17:**- To build a fraction is the reverse of reducing the fraction. Instead of searching for the 1 in a fraction so that you can reduce, you insert a 1 and build.

**Problem 2:**- Create a fraction equivalent to that has a denominator of 33.
**Answer:**- The answer is the fraction .
**Solution:**- Recall that you can multiply any number by 1 without changing the value of the number. (Rule 6). Multiply the fraction by 1.
Recall that 1 has many forms, look for the form of 1 that will result in a denominator of 33.

Since 3 x 11 = 33, use the fraction as 1.

Now can be written as . The product is .

We have created a fraction with a denominator equal to 33 that is equivalent to the fraction . **Check:**- Now prove to yourself with your calculator that your
answer is correct. Calculate 1 divided by 3 and calculate 11 divided by 33; both should yield the same answer. If you are correct, the answers are the same (equivalent) and you have successfully built a fraction.
