Asap. explain how ratios can be written as a fraction. which value is the numerator and which is the denominator of the fraction? give an example.

Say you had 2:1 you would change that into a fraction by taking the number on the left as the numerator and the number on the right as the denominator like 2/1
or
you could do 2:1 and add the numbers together which is 3 then that will be the denominator and just put a 1 on top like this 1/3
