Paulo can eat one and a half of his mother's pies in 45 minutes. how many minutes would it take him to eat half a pie?

First, let's figure out how long it takes him to eat one of his mother's pies.  We do this by finding the number we multiply 1 1/2 to get 1, then we 45 minutes by the same number.  We multiply 1 1/2 by 2/3 to get 1, so let's multiply 45 my 2/3rd.  This is equal to 30 minutes.  So, Paulo can eat one of his mother's pies in 30 minutes.  From this information, it is clear that he can eat half a pie in 15 minutes.
