conversations.value: There were 600 people in the stadium when the football game started. Before the game was over, one-fourth of the boys and one-eighth of the girls left early. How many people remained to see the end of the game if there were 240 girls at the beginning of the game?

conversations.value: There were 600 - 240 = 360 boys at the beginning of the game.
  So, 360 x 1/4 = 90 boys left early.
  And 240 x 1/8 = 30 girls left early.
  A total of 90 + 30 = 120 people left early.
  Therefore, 600 - 120 = 480 people remained to see the end of the game.
