4.4Properties of Proportion. Geometric Mean

In this Math tutorial, you will learn:

  • What are the properties of proportion?
  • How do we use the properties of proportion to solve problems easier?
  • How do we calculate the n-th proportional in a set of numbers participating in a proportion?
  • What is geometric mean? Where does it differ from the arithmetic mean?
  • How to extend the use of geometric mean if more than two numbers are present?

Introduction

In the previous tutorial, we introduced and discussed proportion as a structure containing two or more equal ratios, and its types. Now we will look in more detail at the properties of proportion with the focus on "direct proportion" as the main type of proportion. This is because the inverse proportion is based on the direct proportion, we simply invert down the second ratio.

Another concept discussed in this tutorial is that of geometric mean - a useful tool related to proportions, especially in banking and finance. Moreover, a number of examples are provided with each concept or property to allow a better understanding by you, the reader.
