Saying large numbers (A1-A2)

When do we say the word and with large numbers?  How do we pronounce it?

Listen and repeat the numbers in the table.

???,??? and ??,??? ?,??? ??? and ?? ?
5 five
45 forty- five
345 three hundred and forty- five
1,345 one thousand three hundred and forty- five
13,345 thirteen thousand three hundred and forty- five
51,345 fifty-one thousand three hundred and forty- five
751,345 seven hundred and fifty-one thousand three hundred and forty- five

We use the word and after the word hundred, for example:

345 = three hundred and forty-five
1,345 = one thousand three hundred and forty-five.

When we're saying numbers, we don't say /ænd/.  Instead, we say /ən/:

345 = three hundred and /ən/ forty-five
1,345 = one thousand three hundred and /ən/ forty-five.
751,345 = seven hundred and /ən/ fifty-one thousand three hundred and /ən/ forty-five.

This is because and isn't an important word here so we don't need to pronounce it fully.  The important words are the numbers, which we pronounce fully and a little louder than /ən/:

345 = THREE HUNDRED /ən/ FORTY-FIVE.
1,345 = ONE THOUSAND THREE HUNDRED /ən/ FORTY-FIVE.
751,345 = SEVEN HUNDRED /ən/ FIFTY-ONE THOUSAND THREE HUNDRED /ən/ forty-five.

Knowing the difference between /ænd/ and /ən/ makes it a lot easier to understand long numbers when you hear them.

Numbers in written form

Look at the numbers below. When do we use a comma?

1,345
13,345
51,345
751,345

We use a comma to separate thousands and hundreds, for example:

1,345 =  one thousand (,) three hundred and forty-five.

There are always three numbers after a comma.

The full pronunciation of and /ænd/ is called the strong form

/ən/ is a weak form

There are many weak forms in English and the schwa /ə/ is used a lot. 

Understanding the difference in sound between strong and weak forms can really help you to improve your listening skills.  Tell me more!
