Hello. This isn’t Mathematics, so I don’t get what are you asking this in the Spanish subject.
Answer:
los
Explanation:
its masculine and its plural
Explanation:
Maybe try thinking of it in terms of English first. Like she did that, we did that, you did that.
estar is the equivalent of was
tener is the equivalent of had
Based on that, it should be fairly easy to brainstorm a few ideas
ex. She was funny. He had a party. Etc.
Please let me know if you have any questions
Hoy es 22 de mayo is the way to say it.
