Using plural definite article + number + noun

We can use the plural definite article + number + noun (plural) in order to give an accurate quantity.

Read and listen to these examples:

Note that in the examples above, the number is invariable and never changes its form.

One hundred and one hundred and something

Read and listen to these examples:

Notice how "cien" is invariable, but when it is over one hundred it changes to "ciento".

Also notice that, as with all numbers, "uno" becomes "un" when there is a masculine noun after it (e.g. payasos).

Now, have a look at these examples:

Note that in the examples above, whole hundreds from 200 onwards (200, 300, 400, 500, 600, etc.) agree with the noun they refer to.

Be careful because when we use "non-whole" hundreds like 203, 345, etc., the tens and units do not change, just the hundreds.

Finally, there are some cases where we can use this structure:

For example:

In the example from above, siete works as a noun and therefore takes the plural form to agree with the definite article los.
