Multiplying a fraction by a number which doesn't change the size of the fraction?
One can take many forms
Rationalising the denominator
Summary
Description
This video is another in the Year 10 Advanced course looking at surds. Having looked at how to add, subtract, multiply and divide them I finish this video looks at what it means to rationalise the denominator. Convention states that we're not permitted to have a surd on the bottom of a fraction and so we use a simple, but effective, trick to help "get rid of the the surd". There are a number of examples throughout this video all explained using clear and easy to understand language.
