Before we get started in the fraction to percentage conversion, let"s go over some very quick fraction basics. Remember that a numerator is the number above the fraction line, and the denominator is the number below the fraction line. We"ll use this later in the tutorial.
You are watching: 12/15 as a percentage
When we are using percentages, what we are really saying is that the percentage is a fraction of 100. "Percent" means per hundred, and so 50% is the same as saying 50/100 or 5/10 in fraction form.
So, since our denominator in 12/15 is 15, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:
100 ÷ 15 = 6.6666666666667
Once we have that, we can multiple both the numerator and denominator by this multiple:
12 x 6.6666666666667/15 x 6.6666666666667=80/100
Now we can see that our fraction is 80/100, which means that 12/15 as a percentage is 80%.
We can also work this out in a simpler way by first converting the fraction 12/15 to a decimal. To do that, we simply divide the numerator by the denominator:
12/15 = 0.8
Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:
0.8 x 100 = 80%
And there you have it! Two different ways to convert 12/15 to a percentage. Both are pretty straightforward and easy to do, but I personally prefer the convert to decimal method as it takes less steps.
I"ve seen a lot of students get confused whenever a question comes up about converting a fraction to a percentage, but if you follow the steps laid out here it should be simple. That said, you may still need a calculator for more complicated fractions (and you can always use our calculator in the form below).
