Adding & Subtracting Fractions Test #1

In this Section:



In this section, we learn how to add and subtract fractions. In the first scenario, we will be looking at adding and subtracting fractions with a common denominator. This is the easier scenario. For this case, we will add or subtract the numerators of the fractions and place the result over the common denominator. Once this is done, we look to simplify the fraction. In the second scenario, we will be looking at adding and subtracting fractions without a common denominator. This is the more tedious and difficult scenario. For this case, we will first need to find the least common denominator or LCD. We then rewrite each fraction as an equivalent fraction with the LCD as its denominator. Once this is done, we add or subtract numerators and place the result over the common denominator. We then finish up by simplifying if necessary.
