Exercise 13 Page 286

In the given expression, we have two mixed numbers. 17* 5 56 * 1 14 Before we evaluate such expressions, we should rewrite the expression so that all of the numbers are fractions. We can rewrite any mixed number into a fraction using the following method. Let's first rewrite our expression so that all of the numbers are fractions!
