Description
  • From politics to cookery, ratios, proportions and percentages are part of everyday life. This unit is designed to help you become more familiar with how figures can be manipulated, then you can check whether that discount really is as big as they claim!<link rel="canonical" href="http://www.open.edu/openlearn/science-maths-technology/mathematics-and-statistics/mathematics-education/ratio-proportion-and-percentages/content-section-0" /> First published on Fri, 01 Aug 2008 as <a href="http://www.open.edu/openlearn/science-maths-technology/mathematics-and-statistics/mathematics-education/ratio-proportion-and-percentages/content-section-0">Ratio, proportion and percentages</a>.

  • <p>The topics in this free course, <i>Ratio, proportion and percentages</i>, 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:</p><p>&#xA0;25% of the village population are children;</p><p>or as a ratio:</p><p>&#xA0;&#xA0;one in every four people is a child <i>or</i> there is 1 child for every three adults;</p><p>or a proportion:</p><p>&#xA0;&#xA0;the proportion of children in the village population is a quarter.</p><div class="oucontent-box oucontent-s-heavybox1 oucontent-s-box "><div class="oucontent-outer-box"><h3 class="oucontent-h3 oucontent-heading oucontent-nonumber">Enrol to get a record of achievement</h3><div class="oucontent-inner-box"><p>By enrolling on this course and setting up a free Open University account&#xA0;you&#xA0;can track your progress in My OpenLearn.&#xA0;When you’ve finished you can print off the free&#xA0;<b>activity record</b>&#xA0;to demonstrate your learning.&#xA0;</p></div></div></div><p>This OpenLearn course provides a sample of Level 1 study in <span class="oucontent-linkwithtip"><a class="oucontent-hyperlink" href="http://www.open.ac.uk/courses/find/mathematics-and-statistics">Mathematics &amp; Statistics</a></span>.</p>
