Chapter 13: Fractions

13.1 Introduction

When you follow a recipe to prepare a meal, you are likely to calculate the amount of each ingredient using fractions. Imagine you have friends coming over for dinner. You will have to multiply the amounts in the recipe to make sure there is enough for yourself and all the guests. The skill of multiplying fractions will be very handy in this case.

In this chapter, you will learn more about fractions and percentages. You will solve problems to understand what these numbers are used for. If we only use whole numbers, we cannot always describe quantities precisely. Fractions were invented so that any quantity can be described accurately.
