conversations.value: Can you give me some step-by-step instructions for this math problem: Of the 90 people on William's bus, 3/5 were Dutch. Of the 1/2 of the Dutch who were also American, 1/3 got window seats. What's the number of Dutch Americans who sat at the windows?

conversations.value: On the bus, the number of Dutch people was 3/5 of the total number, a total of 3/5*90 = 54 people.
  Out of the 54 people who were Dutch, 1/2 were Dutch Americans, a total of 1/2*54 = 27 people.
  If 1/3 of the passengers on the bus identifying as Dutch Americans sat at the windows, their number is 1/3*27 = 9
