Question

How do you find ratios?

Answer 1

For example, if there are 5 blue balls and 7 red balls. the ration of the blue balls with the red balls is

`5\colon7`

it can also be written as a fraction :

`(5)/(7)`

It is important to put the one that was mentioned first in the numerator. in this case is blue ball, that's why 5 came first. If we are asked what is the ratio of the red balls with the blue balls , then we will have to indicate 7 first. The ratio will have to be

`\begin{gathered} 7\colon5 \\ or \\ (7)/(5) \end{gathered}`

The sequence is important.
