Hello, again.

In this video, we’re going to learn how to express decimal numbers in English.

And..I’ll tell you it’s quite easy.

let’s look.

Now here is the decimal point.

Don’t call it “period”.

Don’t call it “dot”.

It’s a “point”.

It’s called the ‘decimal point’.

So we would express this number as “one point one”.

Easy.

The next number.

Ok, we could actually express this number two ways.

“One point twelve.”

“One point twelve.”

Or…

“One point one two.”

Ok…

The next number.

“Four hundred point one.”

Easy.

The next number.

Starts with a ‘zero’.

Again, there’s two ways to express this.

You could say, “Zero point zero two.”

Or another common way….because it starts with a zero, we just start with the point.

So some people say, “Point zero two.”

Ok…

Now remember, “zero” can also be called “oh”.

So you could say, “Point oh two.”

The next number here.

Ok, we have more numbers.

So, “Six point zero three three.”

Or, “Six point oh three three.”

Ok…

Ok, let’s move down to the last two numbers here.

We have “ten point one” and “ten point nine”.

Now, “ten point one” is very close to ‘ten’.

Ok…

So, if we change “ten point one”…just change it to only ‘ten’, that’s called ’round down’.

Ok…

“Round down.”

So, the closer….’ten point one’ is very close to ‘ten’, so we take away the ‘point one’ and just have ‘ten’.

“Round down.”

“Ten point nine” is close…very close to ‘eleven’, so we change ‘ten point nine’ to ‘eleven’.

That situation is called “round up”.

Ok, so changing “ten point nine” to ‘eleven’; round up.

‘Ten point one’ to ‘ten’; round down.

Alright…

So, I hope you understand how to use the decimal point.

And I hope you understand ’round up’ and ’round down’.

Let’s take a look at a few examples.

2:48 [Part 2 – Example Sentences]

Alright, the first example.

“There are two point two grams of fat in this food.”
“There are two point two grams of fat in this food.”

The next example.

“I got ninety-nine point nine out of one hundred points on the test.”
“I got ninety-nine point nine out of one hundred points on the test.”

And the last example.

“My brother is one hundred and fifty point five centimeters tall.
“My brother is one hundred and fifty point five centimeters tall.

3:39 [Part 3]

Alright, I hope you have a better understanding of how to use a decimal point.

Before we go, I’m going to talk about the other ‘points’ that we might see in English.

Now up here, …ahh…we have a point here, but we don’t say “point”.

Ok…

Here, it’s going to be “dot”.

Ok, we use ‘dot’ for the internet.

Ok…

So, if your using e-mail it’s “dot com”.

Or…”W-w-w dot gogoteacher dot com.”

Ok, so on the internet, we always say “dot”.

So, “robin at gogoteacher dot com.”

Now here is a sentence and we have another point.

Ok…

In the sentence, this is called a “period”.

Ok…

This is a ‘dot’.

This is a ‘period’.

Ok, so we call that a “period”.

And looking at money…

Ok, we’re going to study money in another video.

But quickly, if we were reading this money, we wouldn’t say “dot” and we wouldn’t say “point”.

Actually, in money, we say, “One dollar ‘and’ twenty-one cents.”

So, in money, don’t say, “One point twenty-one dollars.”

Very strange.

This is “One dollar ‘and’ twenty-one cents.”

Alright and also, you know, in Korean you say ��…��, but in English, this point is called a “mole”.

Ok…

So you have, ‘dot’, ‘period’, ‘and’, ‘mole’.

They all have different names.

Ahh…be careful.

Don’t say the wrong name.

Alright, I hope this video helps you.

See you next time.
