Lesson Menu Five-Minute Check (over Lesson 11–4) Main Idea Key Concepts: Units of Time Example 1:Convert Units of Time Example 2:Use Different Units of Measure Example 3:Use Fractions in Measures

Main Idea/Vocabulary I will convert units of time.

KC

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 = min = h

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.

1.A 2.B 3.C 4.D Example 1 A.120 minutes B.240 minutes C.500 minutes D.720 minutes The track team spends 7,200 seconds in track practice. How many minutes is this?

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.

1.A 2.B 3.C 4.D Example 2 A.1 year 61 weeks B.2 years 8 weeks C.2 years 10 weeks D.3 years 0 weeks Complete: 112 weeks = years weeks.

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 R4 means 4 whole days and 4 hours of another day. 100 ÷ 24 = 4 R4, or Answer: So, 100 h = 4 days 4 hours or 4 days h = d
