Ratio: EVERYTHING you need to know for maths GCSE!

Lots of practice GCSE Maths questions and support over at: https://mathskitchen.com/?utm_source=... This video is all to do with ratios. Perfect to help you with your maths GCSE revision or if you're learning this for the first time! I look at what a ratio is and why we use them, how to simplify a ratio, how to divide an amount in a given ratio, how and why to simplify in the form 1:n and how ratios relate to fractions. One of the skills you need when simplifying ratios is to be able to tell what a number can be divided by and I've done a couple of videos on that:    • Quick maths trick - test of divisibil...      • Easiest way to check if a number divi...   I also mention a quick and easy way to divide any number by four and that can be found here:    • Really quick and easy trick for multi...   Thanks for watching - hope you found it useful.
