Ratio Resolution

Hi everyone my name is Sauma,today you are going to be learning about my Maths task,this is very easy,and simple,well it is mostly talking about Ratio,so which shows colours,for example for that is there is a big wheel,that shows colours,and there are about three colours,and the colours are Blue,Red,Purple,so how many Blues are 3,and how many Reds,are there are 6,and how many Purple,are there are 7,so if I say what is the ratio of blue to Purple?so then you are going to say 3/7,and that is how it works,if you are free please leave a positive comment.
