The fraction 9/36 is a ratio: simplifying this ratio will yield 1/4, which is a ratio (in more formal terms) of 1:4

A ratio can be written 3 ways, like the following:- a to b a:b     a ------   b So, technically 9/36 is in ratio already but you can also write is as:- 9 to 36    or  9:36 Now we can simplify this:-   9  ÷  9          1 ---------------  = --------  36 ÷  9          4 So, 9:36 reduced is 1:4 or 1 to 4, or 1 over 4 (1/4).
