Ratio, proportion and percentages

Introduction

Unit image

The topics in this free course, Ratio, proportion and percentages, are concerned with dividing something into parts. For example, if there are 200 people living in a small village, and 50 of these are children, this could be expressed as a percentage:

 25% of the village population are children;

or as a ratio:

  one in every four people is a child or there is 1 child for every three adults;

or a proportion:

  the proportion of children in the village population is a quarter.
