[Question]The three angles of a triangle add up to 180 degrees. The largest angle is 5 times bigger than the smallest. The middle angle is 3 times bigger than the smallest. How many degrees is the smallest angle?
[Answer]Let x be the smallest angle. The combination of the three is x + 3x + 5x = 9x. Thus 9x = 180. So x = 20. The answer is 20.

Question: James works for 240 minutes. He takes a water break every 20 minutes and a sitting break every 120 minutes. How many more water breaks does he take than sitting breaks?
Answer: First find the number of water breaks James takes: 240 minutes / 20 minutes / water break = 12 water breaks. Then find the number of sitting breaks James takes: 240 minutes / 120 minutes / sitting break = 2 sitting breaks. Then subtract the number of sitting breaks from the number of water breaks to find the difference: 12 breaks - 2 breaks = 10 breaks. The answer is 10.
