In this lesson, Julie Harland teaches an easy way to divide numbers by 5 using a simple two-step process. By either dividing by 10 and then multiplying by 2, or multiplying by 2 and then dividing by 10, you can quickly find the answer. The method works for numbers that end in 0, as well as those that don't. Julie also explains how to use this method to divide by 50 or 500. This is a quick and handy shortcut that can save time and effort while solving division problems.
