conversations.value: John is working as an IT specialist. He repairs broken computers. One day he had to fix 20 computers. 20% of them were unfixable, and 40% of them needed to wait a few days for spare parts to come. The rest John was able to fix right away. How many computers John was able to fix right away?
conversations.from: assistant
conversations.value: From all the computers, 100% - 40% - 20% = 40% got fixed right away.
  So John was able to fix 40/100 * 20 = 8 computers.
