What are the similarities between a quineanera and a sweet 16?

List:
they both celebrate a birthday
it usually shows that a woman is now a adult 
they mostly dance and give gifts

hope this helps :)

I think you mean a Quinceañera, a 16th birthday party of a young Hispanic girl coming of age. This is a family and friends celebration, as much as a sweet 16 would be. But the difference is a Quinceañera is a Hispanic tradition, while anyone can have a sweet 16.
The main similarities are they both happen at 16, they're both to celebrate a young girl's coming of age for their birthday, and they both are surrounded by family and friends.

You have to fry the plantains.

The only change would be to add the accent on esta (on the a) in esta in number 15.
