Maria says that all the numbers in the nineties are composite. jackie says a number in the nineties is a prime. who has the reason? explain your answer.

this is my brothers homework and i don't really get it. it was translated to english from spanish and i would like some so that i can him. explain

I think that Maria would most likely be correct because the number 9 itself is composite, meaning that it can be divided evenly with numbers other than itself and 1.  But in fact, not all number in the nineties are composite. There is only one number in the nineties that is prime. That number is 97. 
So with that said, once again, I think that Maria is mostly correct, but not all numbers in the nineties are composite. Almost all numbers in the nineties are.
