Fractions as a Percent
Hi, I'm Rachel, and today's topic is fractions as a percent. So when we want to convert a fraction into a percent we always want to put it over 100, right? Because percent is always out of 100, right? 100 with some number above it. So let's say that we have the fraction 3/4 right? Because obviously if it's a fraction over 100 already, it's easy to change the percent. So let's start with something like 3/4 right? So we want to put that over 100, so let's put 100 in the denominator. Now 4 times what is 100? Well 4 times 25. So if we multiply this by 25 we get 100. So we can multiply the numerator by 25 to get 75. So that's it as a fraction, 75/100. As a decimal it would look like .75 and as a percent it would be 75%. So you just put it over 100 and then you can write it as that number with the percent sign right after it. And that's turning fractions into percentages. I'm Rachel and thank you very much for learning with me today.
