"Duae puellae dormiunt."

Translation: The two girls sleep.

[HinjakuHinjaku]

How does duo change for different genders/numbers ?

[Moopish]

It is always plural. We use duae here since it has to agree with puellae (which is feminine, nominative, plural).

Case: masculine/feminine/neuter

Nominative: duo/duae/duo

Genitive: duorum/duarum/duorum

Dative: duobus/duabus/duobus

Accusative: duos/duas/duo

Ablative: duobus/duabus/duobus

Vocative: duo/duae/duo

[J.C.M.H.]

Thus it looks better:

Case	masculine	feminine	neuter
Nominative	duo	duae	duo
Genitive	duorum	duarum	duorum
Dative	duobus	duabus	duobus
Accusative	duos	duas	duo
Ablative	duobus	duabus	duobus
Vocative	duo	duae	duo

[Moopish]

That definitely does. Just looked up how to do tables so I never make such a mess again. Thanks.

What you do with the dashes in the second row affects the formatting:

:---: centers

Column number one	Col 02
entry 01	entry number two
entry no. three	entry 4

:--- left-justifies

Column number one	Col 02
entry 01	entry number two
entry no. three	entry 4

---: right-justifies

Column number one	Col 02
entry 01	entry number two
entry no. three	entry 4

Just looks like a long string with no spaces for me

Thanks for answering.

are the other numbers also declensed this way?

[Rae.F]

The verb is "to decline" and the cardinal numbers past 2 do not decline only a very few cardinal numbers decline.

http://latindictionary.wikidot.com/learn:numbers-1

[Moopish]

Three (tres, tria) declines, a thousand is semi-indeclinable, 200, 300, 400, 500, 600, 700, 800, and 900 also decline.

[Rae.F]

My mistake. I didn't look far enough.

[J.C.M.H.]

No, the numbers from quattuor onwards are almost all indeclinable.

[JMcQ455870]

the two girls are sleeping sounds correct also

[Origin5world5_]

Can it also be translated as "two girls are sleeping"?

[Moopish]

I don't see why it couldn't.
