Comparing Fractions Test #1

In this Section:



In this section, we learn how to compare the relative size of two or more fractions. We will learn two different methods. The first method involves converting each fraction into an equivalent fraction where the LCD is its denominator. In this case the denominators are all the same, so we can simply inspect the numerators. The larger the numerator with a given denominator, the larger the fraction. For example, five - eighths is larger than three - eighths. The denominator in each case is eight, so we say the larger fraction is the one with the larger numerator. Five is larger than three, so five - eighths is the larger fraction. The second method is a shortcut known as cross multiplying. With this method, we form cross products and look at the number formed. The larger number will be next to the larger fraction.
