Here we will show you how to convert the ratio 4:15 to a fraction. In other words, we will convert the ratio of 4:15 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. 4:15 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 4:15 is a part-to-part ratio, it means that there are 4 of something and 15 of something else with a total of 19.
To convert a part-to-part ratio such as 4:15 as a fraction, you make the left side of the colon the numerator and the total the denominator:
4:15 → 4/19
Since there are 15 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:
4:15 → 15/19
Part-to-Whole
A part-to-whole ratio of 4:15 means that there are 4 of something and the total is 15. It also means that there are 11 of something else. To convert a Part-to-Whole ratio such as 4:15, you replace the colon with a fraction bar to get this answer:
4:15 → 4/15
Since there are 11 of something else and still the total of 15, you can also make a 2nd fraction like this:
4:15 → 11/15
