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? Think carefully first, then make a decision:
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. So, the answer is 480.
