5. Example 1 Convert Units of Time Students spend about 360 minutes a day in school. How many hours a day do they spend in school? Answer: So, the students spend 6 hours a day in school. To convert smaller units of time to larger units, divide. Since 1 hour (h) = 60 min, divide 360 by 60. 360 ÷ 60 = 6 360 min = h

6. Example 1 Convert Units of Time Check Use mental math to check the answer. 300 min = 300 ÷ 60 or 5 h 420 min = 420 ÷ 60 or 7 h Since 6 hours is between 5 and 7 hours, the answer is reasonable.

8. Example 2 Use Different Units of Measure Answer: So, 72 weeks = 1 year 20 weeks. Since 52 weeks = 1 year, divide 72 by 52 to find the number of years. 72 ÷ 52 = 1 R20 1 R20 means 1 whole year and 20 weeks of another year. Complete: 72 weeks = years weeks.

10. Example 3 Use Fractions in Measure How many days is 100 hours? To convert a smaller unit to a larger unit, divide. Since 24 hours = 1 day, divide 100 by 24. 4 R4 means 4 whole days and 4 hours of another day. 100 ÷ 24 = 4 R4, or 4 1 6 Answer: So, 100 h = 4 days 4 hours or 4 days. 1 6 100 h = d
