Discovery Education: Webmath: Subtract Two Fractions

Have your class demonstrate their ability to compare fractions with this short multiple-choice assessment. Using the fractions 9/8 and 9/4, the students first make comparisons using both words and the greater than/less than signs. Next,...

Sal adds a few more steps to these problems as he solves algebraic equations with two steps, though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...

To subtract mixed numbers, it may be necessary to find the least common multiple to establish a common denominator. This is just what Sal does in this presentation. First, he shows how to find a common denominator and then the process...

So do you really want to know how to find a rational number between two given fractions? The teacher explains how to average the two fractions to find a rational number between the two fractions. There are several steps involved in...

Trying to decide which method to use to compare the value of two fractions? You could find a common denominator, you could turn them into decimals, or you could cross multiply. Let's cross multiply because we like to multiply more than...
