Lesson 4: Decimals in written form# Decimals in written form (hundredths)

To write a decimal in word form, start by writing out the whole number portion. Next, express the decimal portion as a fraction of hundredths. For clarity, it's often helpful to simplify multiple terms (such as "one tenth and five hundredths") into a single fraction (such as "fifteen hundredths").

- whats a good way to rember to go like 10 over 100 after the decimal?

(58 votes)- I always remember by thinking of everything to the right of the decimal as the same thing as the normal place values, except skipping the "ones" place and going in the other direction.(6 votes)

- Khan academy really helps(21 votes)
- when the guy wrote 63.15 in word form, he said: sixty-three and fifteen hundredths. Though I'm not saying he's wrong or anything, but instead of saying "and" do you say "point"? So sixty-three point fifteen hundredths?(13 votes)

- I need help on dividing decimals and fractions.(9 votes)
- Well, I know how to divide fractions. With practice it is simple!

Here is an example:

5/6 divided by 2/5

First, you have to flip the second fraction. So now the second fraction is 5/2 ( which by the way is a improper fraction). Now you turn the division sign into a multiplication sign. So now the equation is 5/6 times 5/2. And now you just multiply the fractions like any other problem and BOOM! you got it. By the way the answer is 25/12 or, simplified, 2 1/12(0 votes)

## Video transcript

We're asked to write this right
here in word form, and I'm not saying it out loud
because that would give the answer away. We have 63.15 that we want
to write in word form. Well, the stuff to the left of
the decimal point is pretty straightforward. Let me actually color code it. So we have 6, 3. Let me do it all in
different colors. And then we have a decimal, and
then we have a 1 and a 5. There's one common way of doing
this, but we'll talk about the different ways you
could express this as a word. But we know how to write
this stuff to the left. This is pretty straightforward. This is just sixty-three. Let me write that down. So this is sixty-three. And instead of the decimal,
we'll write, and. Now there's two ways
to go here. We could say, and one tenth
and five hundredths, or we could just say, look, this
is fifteen hundredths. One tenth is ten hundredths. So one tenth and five hundredths
is fifteen hundredths. So maybe I can write it like
this: sixty-three and fifteen hundredths. Just like that. Now, it might have been a little
bit more natural to say, how come I don't say
one tenth and then five hundredths? And you could, but that would
just make it a little bit harder for someone's brain to
process it when you say it. So it could have been
sixty-three-- so let me copy and paste that. It could be sixty-three and, and
then you would write, one tenth for this digit right
there, and five hundredths. Sixty-three and one tenth and
five hundredths is hard for most people's brains
to process. But if you say, fifteen
hundredths, people get what you're saying. Not to beat a dead horse, but
this right here, this is 1/10 right here and then this
is 5/100, 5 over 100. But if you were to add these
two, If you were to add 1/10 plus 5/100 -- so
let's do that. If you were to add 1/10 plus
5/100, how would you do it? You need a common denominator. 100 is divisible by both 10 and
100, so multiply both the numerator and denominator
of this character by 10. You get 10 on the top and
100 on the bottom. 1/10 is the same thing
as 10 over 100. 10/100 plus 5/100 is equal to
15 over 100, so this piece right here is equal to 15/100. And that's why we say
sixty-three and fifteen hundredths.
