conversations.value: Solve the math problem: Nikka has a 100 stamp collection. Thirty-five percent of her stamps are Chinese, 20% are US stamps, and the rest are Japanese stamps. How many Japanese stamps does Nikka have?

conversations.value: Nikka has 100 x 35/100 = 35 Chinese stamps.
  She has 100 x 20/100 = 20 US stamps.
  So, Nikka has 35 + 20 = 55 stamps that are not Japanese.
  Thus, Nikka has 100 - 55 = 45 Japanese stamps.
