Introduction to Representing Parts of a Whole as Fractions

A photo of several bakers at work on a table in a classroom setting. Bakers combine ingredients to make delicious breads and pastries.
Often in life, whole amounts are not exactly what we need. A baker must use a little more than a cup of milk or part of a teaspoon of sugar. Similarly a carpenter might need less than a foot of wood and a painter might use part of a gallon of paint. In this module, we will learn about numbers that describe parts of a whole. These numbers, called fractions, are very useful both in algebra and in everyday life. You will discover that you are already familiar with many examples of fractions!  

Learning Outcomes

By the end of this section, you will be able to:
  • Represent parts of a whole as a fraction with models, numbers, and words
  • Identify the numerator and denominator of a fraction
  • Model improper fractions and mixed numbers
  • Convert between improper fractions and mixed numbers
  • Model equivalent fractions
  • Find equivalent fractions
  • Locate fractions and mixed numbers on the number line
  • Order fractions and mixed numbers
  Before you get started in this module, try a few practice problems and review prior concepts.
