In which one of the following sentences is the number written correctly?
a the college has an endowment of more than $187 million.
b the parcel of land was advertised as two hundred forty-three and three-quarters acres.
c one hundred and thirty-two people lined up to buy the tickets.
d john just paid $33 thousand for his new car.

There are actually two correct answers in this question.
The first correct answer is A - The college has an endowment of more than $187 million. 
The second correct answer is C - One hundred and thirty-two people lined up to buy the tickets. 

The reasons I chose two answers is that the rules for writing large numbers are complex and not everyone agrees with the same rules. The one rule that everyone agrees with is the rule that the writer needs to be consistent in the way he spells out numbers in a sentence.
