英文仙怎麼寫的?

usually written as:
One Hundred Fifty Four Dollars and Twenty Cents

but if you are writing a cheque, there is usually "HKD" in front, then you will write:
(HKD) One Hundred Fifty Four and Cents Twenty

1. definitely incorrect.
2. acceptable. But it's never said that way.

In conversation. one would say one of the following. And let me tell you when and why:

1. a hundred fifty four dollars and twenty.
AND is usually omitted in conversation by Americans.

2. a hundred fifty four bucks twenty.
This is even more informal. But this is what will always hear.

3. One Hundred And Fifty-Four Dollars Twenty Cents.
Only for writing cheques. It's preferable to put AND before DOLLARS and not CENTS. But between dollars and cents are also acceptable.

But e.g. 20c or $0.20, one would simply say twenty cents.

NB: British uses Pounds (or informally, quid) and Pence.

2.one hundred fifty four and twenty cents
