for example if you have 2:5:8
all you do is add them together and divide it by how many numbers theyr are
so 2+5+8=15
15/3=5
so the answer is 5.

How do you explain ratio?
a ratio is a comparison between 2 or more things. To work ratio out, it will be easier if you separate it into parts. if you was to work out the ratio of money, you would add the ratio together. whatever the number is you convert into money. you would then times it by the first number of the ratio which is the answer of the first of the first part, then you add it to the second number, and then that is the answer to the ratio problem. This is an example: if you had to work out £100 and the ratio was 8:2 this is how you would do it. first part you add the 8 and the 2 together which is 10, convert that into money it is £10 second part you times the 8 and the £10 together which is £80 third part you times the 2 and the £10 together which is £20 then you put it in ratio which is £80:£20

Simplify the ratio 0.5 to 0.75?
Begin with the ratio 0.5 : 0.75 Multiply both parts of the ratio by 2: 1 : 1.5 You can multiply by two again: 2 : 3 Both of these are simplified compared to the original. Which one is used depends on how the ratio is being used. Some ratios are easier to work with and understand with whole number so 2 : 3 would be used. In other cases, using 1 as part of the ratio makes it easier to work with, so then 1 : 1.5 may be used. All of them describe the same ratio.
