Hello, and welcome to Study English, IELTS Preparation. I'm Margot Politis.

0:18

In the Listening Module of the IELTS Test you can expect to be asked questions about

0:23

numbers.

0:24

So it's important to be familiar with how we talk about numbers.

0:28

First, listen to the numbers in this clip about a wind farm in Tasmania:

0:34

Each tower that you can see can generate enough power for between seven and eight hundred

0:40

houses.

0:40

'between seven hundred and eight hundred houses'

0:45

When numbers are exact or a clear approximation such as 'between seven hundred and eight hundred',

0:52

the word 'hundred' has no final 's'. The plural is formed by the following noun: 'between

1:00

seven hundred and eight hundred houses'.

1:05

For an exact figure you say: seven hundred houses.

1:10

You can use a preposition to be less exact and say: over seven hundred houses; around

1:17

seven hundred houses; about seven hundred houses; nearly seven hundred houses or under

1:27

seven hundred houses.

1:28

When we state a number, such as seven hundred or eight thousand there is no 's' after the

1:37

unit - four hundred, ten thousand, or five million.

1:43

So when do we add 's' to these words?

1:47

Listen to the man in the next clip use 'hundreds' to describe the slow change from one type

1:53

of forest to another:

1:56

There have probably been three lots of logging since white settlement in the 1860s. In time,

2:01

that eucalyptus forest will gradually go back to rainforest, but that takes hundreds of

2:06

years.

2:07

'Hundreds of years'. There is no number; it's just more than one. Notice we add 'of' before

2:15

the noun 'years' Hundreds of years.

2:21

So listen carefully. 'Thousands of' and 'millions of' are not exact numbers. They're guesses

2:30

or rough figures.

2:32

He also said the 1860s. This means any year from 1860 to 1869.

2:42

In the next clip about Angkor Wat in Cambodia, the speaker doesn't use the final 's'.

2:49

Angkor is one of the most popular World Heritage sites in the whole of Asia. Every year now

2:53

there are over one million tourists coming to Angkor.

2:57

By saying 'over one million tourists', he means more than one million but much less

3:04

than 2 million. If the figure were closer to two million, he would probably say 'nearly

3:11

two million tourists'

3:12

But if he'd said millions of tourists, he would mean more than 2 million.

3:19

Instead of saying one million you can also say a million. It means the same thing.

3:26

Listen to this woodchopper talking about how many titles he's won:

3:31

I've won one hundred and eighty three world titles I suppose, the only person in sporting

3:36

history to ever win over a thousand championships … so I suppose it hasn't been too bad

3:41

of a life.

3:41

'Over a thousand championships'. He could have said one thousand or a thousand. And

3:50

he could have said a hundred and eighty three. Notice that 'and' is used to add numbers below

3:57

a hundred - he says one hundred and eighty three.

4:03

You also say a thousand and 83 (1,083) and a million and 83 (1,000,083). But you say

4:11

one thousand, one hundred and 83 (1,183) or one million, one thousand and 83 (1,001,083).

4:20

When you're talking about where something occurs in a sequence, you use ordinal numbers

4:28

such as first, second, third, fourth.

4:34

Ordinal numbers are used in dates, as in this clip in which the speaker is talking about

4:39

a major art exhibition held in 2006.

4:43

The Biennale of Sydney this year is the 15th. It occurs every two years, as all biennales

4:52

do and this year starts on the 8th of June.

4:57

He says 'the fifteenth'. He means the fifteenth Sydney Biennale exhibition. There have been

5:04

14 held before this one. The date is the eighth of June. This date can be expressed like this:

5:14

June eighth June the eighth

5:17

Now listen for another use of an ordinal number in this clip about an art course held in an

5:23

art gallery:

5:24

So if we're looking at one of the paintings in this gallery in European art, where we're

5:29

looking at 19th-century paintings, we're talking about the paintings as they appear in the

5:34

gallery spaces.

5:36

She says: '19th century paintings'.

5:40

Ordinal numbers are used for centuries and are often written in numbers like this:

5:46

19th

5:48

Of course, this refers to the 1800s, again usually written as a number: the 1800s.

5:55

So what do you call the present century?

5:59

I think that the strongest mark of 21st century culture is artists taking from every possible

6:06

place to realise their visions.

6:08

He says: '21st century culture'. The suffix 's-t' is used after 1 to represent the last

6:17

2 letters of 'first'.

6:23

Ordinal numbers are also used to refer to fractions.

6:28

You have the special fraction terms - half, third and quarter, but all other forms use

6:36

ordinal numbers as in this clip about the wind farm:

6:40

Six towers were erected in that time; these have the potential of generating one fifth

6:45

of Tasmania's power needs from wind energy.

6:48

'One fifth of Tasmania's power needs'.

6:53

Plural fractions take a plural form, for example: two fifths. Fractions are followed by 'of':

7:03

one fifth of. And a noun group which refers to the whole: one fifth of Tasmania's power

7:11

needs.

7:13

Another type of fraction is percentage. For example, 'one-quarter' (1/4) can be expressed

7:21

as 25%.

7:24

Let's listen for the percentage used in this clip about an oyster farm:

7:28

It takes approximately 2 to 2 and a half years to get the oysters up to size and sold to

7:33

the market. From this farm we've averaged about 15% of the market for export and that

7:38

goes to Hong Kong and Japan.

7:40

'fifteen percent of the market'.

7:43

Percentages have the same structure as fractions, 'of' and a noun group: Fifteen percent of

7:54

the market for export.

7:59

Yet another way of talking about parts of numbers is decimals.

8:05

Listen to how they're used in talking about wind turbines:

8:08

It's quite a large structure. 1.75 megawatts generated by each unit.

8:13

'1.75 megawatts'.

8:17

Electrical power is measured in 'watts'. One megawatt is one million watts.

8:25

You say one point seven five, but write it in numbers with a decimal point: 1.75.

8:35

A decimal is usually followed by a plural noun: '1.75 megawatts'

8:43

Now let's listen to a furniture maker talk about the thickness of the veneer, or layer

8:49

of wood he puts on his furniture. Is his veneer thicker than the old fashioned sort?

8:55

Today we're using sophisticated ways of putting our construction of our furniture. We use

8:59

a lot of veneers and those veneers aren't the old-fashioned .06 of a mil, they're about

9:05

a 6 mil veneer and they're laid up on MDF and they have a solid frame.

9:10

His veneers 'aren't the old-fashioned .06 of a mil'. They're 'about a 6 mil veneer'.

9:17

They're much thicker.

9:19

'Point 06 of a mil' is a decimal figure. It's less than one. Mil is short for millimetre.

9:28

Notice that he says it like a fraction - point 06 of a mil.

9:34

Usually you say point 06, although you will sometimes hear point zero six.

9:41

That's all for today.
