How to Simplify Ratios
Following is how to simplify ratios in simplest form step by step.
To simplify two numbers A and B
1. Find the greatest common factor (gcf) of A and B
2. ratio A = A/GCF
3. ratio B = B/GCF
For example, to simplify 20:45, first find the greatest common factor.
1. GCF = 5
2. ratio A = 20/5 = 4
3. ratio B = 45/5 = 9
The ratio in simplest form is 4/9.
