Ratios can be part-to-part, part-to-whole,<span> or </span>whole-to-part.<span> Let's take a look at what this means.</span>
When we compare boys to girls in a classroom, we are comparing part of the class to another part of the class. This would be a part-to-part comparison.
When we compare boys to the whole class, this is a <span>part-to-whole </span>comparison.
If we were to compare the class to the girls, this would be whole-to-part comparison.
EXAMPLE: A class is made up of 14 girls and 15 boys.
PART_TO_PART 14 : 15 shows girls to boys
PART_TO_WHOLE 14: 29 shows girls to the class
Whole-to-Part 29 : 14 shows the class to the girls
