W05 Math Exercises: Division and Percentages

Overview

This week you were taught how to perform long division. We are blessed in this modern age to have calculators to do arithmetic for us, however, it is still important to know how to do division problems without a calculator. For this reason, we encourage you to practice doing division by hand this week. Doing division strengthens your multiplication skills and we highly recommend you memorize your multiplication facts at least up to 9x9. This will be a tremendous help to you when you study fractions.

Use these exercises to help you strengthen your division skills. You can do this by taking the exercises over and over again.
