Limitations of Ratios

Well by now you should be able to:


  • List what they are - all nine and recall their equation here and here
  • Use them in context using real data from a real case study
  • Explain what they tell you about the information given
Top Tip for doing calculations in the exam


  1. Recall equation and write it down (1m)
  2. Drop in the numbers by writing it down (1m)
  3. If the numbers don't fit you clearly have the wrong equation so start again
  4. Do the calculation showing all workings (1m)
  5. Show the answer clearly - underline it or circle it (1m)
Easy peasy
