![]() When you put it in simplified form, it's 9/50. Or you could immediately say that 18% as a fraction is 18/100. So if we move the decimal to the left two spaces, one, two, this becomes 0.18. But if you want to express this as a decimal without the percent, you just move the decimal to the left two spaces. I just added a trailing zero there, just so that you see the decimal, really. And another way to think about it, you could view this as 18.0%. But if you ever were to see this in a problem, the fast way to do this is to immediately say, OK, if I have 18%, you should immediately say, anything in front of the percent- that's that anything, whatever this anything is- it should be equal to that anything. Now, I went through a lot of pain here to show you that this really just comes from the word, from percent, from per 100. So we have 18% is the same thing as 0.18, which is the same thing, in simplest form, as 9/50. So this is the fraction in simplest form. And I don't think these guys share any common factors. And we're going to get 18 divided by 2 is 9. So we have 18 divided by 2 over 100 divided by 2. And they're both even numbers, so we know they're both divisible by 2, so let's divide both the numerator and the denominator by 2. ![]() And if we write it as a simplified fraction, we need to see if there is a common factor for 18 and 100. You could view this as 1 tenth and 8 hundredths, which is the same thing, or 10 hundredths and 8 hundredths, which is 18 hundredths. And we know how to write that in decimal form. Let's do the decimal first, just because that's actually what I said I would do first. ![]() From here we can go straight to a decimal or we could do this fraction in simplest form. This literally means 18 per 100, or 18 hundredths. We're literally doing the fraction first. 18 per 100 as a fraction literally means 18/100. Actually, I said I would do the decimal first, but we can start putting it into a fraction first. I'm actually separating out the percent, it's only going to be one word, but I'm writing it as, literally, per cent. So 18% is the same thing as 18 per 100, or 18 per cent. 0:00 Write 18% as a decimal and as a fraction in simplest form.
