conversations.value: There are 20 dolphins in the aqua park. One-fourth of the dolphins are fully trained. Two-third of the remaining dolphins are currently in training and the rest will be trained next month. How many dolphins will be trained next month?
  Give me a clear explanation.

conversations.value: 20 x 1/4 = 5 dolphins are fully trained.
  So, 20 - 5 = 15 dolphins are not yet fully trained.
  15 x 2/3 = 10 are currently in training.
  Therefore, 15 - 10 = 5 dolphins will be trained next month.
