Hi, I'm Rachel, and today we're going to be going over how to turn a fraction into a decimal using denominators 10 or 100. If we have a number like three over 10, that's it written as a fraction, and if we want to think of it as a decimal, we can say that's three tenths. The first number, the first digit after the decimal is the tenths place. So we're just gonna write .3, that's three tenths. If we have three over 100, that's the number as a fraction, we want to turn it into a decimal. The first is the tenths place, the second is the hundredths place. So it's three hundredths, we're going to put it in the hundredths place, and then we're just going to put a zero in the tenths place, because that's the number before three, right? There's nothing, it's zero. If we have 30 over 100, well that's the same as three tenths, right? If you reduce it? So again, that's .3. You can write it as .30, it's the same thing. .30, right? Over 100, you can say that's the hundredths place, but you don't need to write a zero, because it's after the decimal. So you don't actually need to have that, you can just write .3. I'm Rachel, and thanks for learning with us today.
