You are watching: What percent is 21 out of 25

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 21/25 is 25, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:

100 ÷ 25 = 4

Once we have that, we can multiple both the numerator and denominator by this multiple:

21 x 4/25 x 4=84/100

Now we can see that our fraction is 84/100, which means that 21/25 as a percentage is 84%.

We can also work this out in a simpler way by first converting the fraction 21/25 to a decimal. To do that, we simply divide the numerator by the denominator:

21/25 = 0.84

Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:

0.84 x 100 = 84%

And there you have it! Two different ways to convert 21/25 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).
