Rationalising powerpoint

Hopefully this will help! It has the description of rationalising, the easiest way to find them, changing recurring decimals to fractions and rationalising the denominator. Again I went over the top with the animation but it looks good. If any of the topics that you know you struggle with open the powerpoint then go and do some questions on it on maths websites or past papers. Good luck with your exam!
