Letter From Gotham tells me this story:
They ask a bunch of Americans to divide some fractions-as in 12/15 by 20/52 or something. None of them get it right, except two immigrants. One was a black woman from the West Indies. The other a Polish street sweeper. The interviewer asks how they knew the answer. They were like: "I went to school."
