You are watching: What percentage is 3/8
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 3/8 is 8, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:
100 ÷ 8 = 12.5
Once we have that, we can multiple both the numerator and denominator by this multiple:
3 x 12.5/8 x 12.5=37.5/100
Now we can see that our fraction is 37.5/100, which means that 3/8 as a percentage is 37.5%.
We can also work this out in a simpler way by first converting the fraction 3/8 to a decimal. To do that, we simply divide the numerator by the denominator:
3/8 = 0.375
Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:
0.375 x 100 = 37.5%
And there you have it! Two different ways to convert 3/8 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).
