Here we will show you how to convert the ratio 8:9 to a fraction. In other words, we will convert the ratio of 8:9 to a fraction with a numerator and a denominator.
There is actually more than one answer to this problem, depending on what kind of ratio it is. 8:9 can either be a Part-to-Part ratio or a Part-to-Whole ratio. We will describe and convert both types of ratios to fractions.
Part-to-Part
A part-to-part ratio is the most common form of ratio. If the ratio 8:9 is a part-to-part ratio, it means that there are 8 of something and 9 of something else with a total of 17.
To convert a part-to-part ratio such as 8:9 as a fraction, you make the left side of the colon the numerator and the total the denominator:
8:9 → 8/17
Since there are 9 of something else, you can also make another fraction where the right side of the colon is the numerator and once again the total is the denominator:
8:9 → 9/17
Part-to-Whole
A part-to-whole ratio of 8:9 means that there are 8 of something and the total is 9. It also means that there is 1 of something else. To convert a Part-to-Whole ratio such as 8:9, you replace the colon with a fraction bar to get this answer:
8:9 → 8/9
Since there is 1 of something else and still the total of 9, you can also make a 2nd fraction like this:
8:9 → 1/9
