# Writing decimals in words

For example, the place value of the 4 in So this is four tens and three hundredths. And if you're saying well wait a minute, this looks like two tenths and four hundredths, you'd be right! We can continue with smaller and smaller values, from tenths, to hundredths, and so on, like in this example: Have a play with decimal numbers yourself: Large and Small So, our Decimal System lets us write numbers as large or as small as we want, using the decimal point.

So we're going to have four tens. Let's do another one of these, this is kinda fun.

## Write the decimal 0.25 in words

And of course 20 hundredths and four hundredths is the same thing as 24 hundredths. The place-value chart can be extended to include numbers less than one, which are sometimes called decimal fractions. So four tens, which is the same thing as 40, and three hundredths right over here, so 40 point zero three. A decimal point is used to separate the whole number part of the number and the fraction part of the number. How could I say this number? And like always, try to pause the video and try think about it on your own. And to make that intuition of how we could just call this 17 hundredths instead of just calling it one tenth and seven hundredths, let's actually count by hundredths. When we write numbers, the position or "place" of each digit is important. What is 10 times smaller than Ones? So hopefully that makes sense. I hope that doesn't confuse you, but we could keep counting. Well not I could just add these hundredths, if I have 10 hundredths and I have another seven hundredths, that's going to be 17 hundredths.

Not tenths, four tens. Well 10 hundredths, let me write it this way, 10 hundredths is the same thing as one tenth. So that is one hundredth, that is two hundredth, and actually, let me just go straight to nine hundredths. Now once again, 10 hundredths is the same thing as one tenth, just the same way that 10 ones is the same thing as one Introduction In addition to fraction notation, decimal notation is another way to write numbers between 0 and 1. Or, in measuring the length of a room, you may find that the length is between two whole numbers, such as Now another to think about it is just say the whole thing in terms of hundredths. What you want to examine now are the place values of the decimal part, which are underlined in the chart below.

What is 10 times smaller than Ones? So if we go from nine hundredths, the next, if I'm counting by hundredths, the next one's going to be 10 hundredths.
