I will convert units of time. Main Idea/Vocabulary
360 min = h Convert Units of Time Students spend about 360 minutes a day in school. How many hours a day do they spend 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 Answer: So, the students spend 6 hours a day in school. 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. Example 1
A B C D The track team spends 7,200 seconds in track practice. How many minutes is this? • 120 minutes • 240 minutes • 500 minutes • 720 minutes Example 1
Complete: 72 weeks = years weeks. Use Different Units of Measure 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. Answer: So, 72 weeks = 1 year 20 weeks. Example 2
A B C D Complete: 112 weeks = years weeks. • 1 year 61 weeks • 2 years 8 weeks • 2 years 10 weeks • 3 years 0 weeks Example 2
100 h = d 1 100 ÷ 24 = 4 R4, or 4 6 1 Answer: So, 100 h = 4 days 4 hours or 4 days. 6 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. Example 3
A B C D How many weeks is 33 days? • 3 weeks 11 days • 4 weeks • 4 weeks 5 days • 5 weeks 2 days Example 3
