Fractions of time units

Learning Objectives Identify the total number of smaller units within a larger time unit (e.g., 60 minutes in an hour). Calculate a fraction of an hour in minutes (e.g., 1/2 of an hour). Calculate a fraction of a minute in seconds (e.g., 3/4 of a minute). Convert mixed numbers of time units into a single smaller unit (e.g., 1 and 1/2 hours to minutes). Solve one-step and two-step word problems involving fractions of time. Determine what fraction of a larger unit a smaller unit represents (e.g., 15 minutes is 1/4 of an hour). Ever heard someone say, 'See you in a quarter of an hour'? 🤔 Let's figure out exactly how many minutes that is! In this lesson, we will learn how to use fractions to talk about parts of an hour and parts of a minute. This is a super usef...

TermDefinitionExample Time UnitA standard measurement of time. The main units we will use are hours, minutes, and seconds.An hour is a time unit. A minute is a smaller time unit. FractionA number that represents a part of a whole. It has a numerator (top number) and a denominator (bottom number).1/2 means one part out of two equal parts. ConversionChanging a measurement from one unit to another without changing its value.Converting 1 hour to 60 minutes. DenominatorThe bottom number of a fraction that tells you how many equal parts the whole is divided into.In the fraction 3/4, the denominator is 4. It means the whole is split into 4 equal parts. NumeratorThe top number of a fraction that tells you how many of the equal parts you have.In the fraction 3/4, the numerator is 3. It means you h...

Fraction of an Hour to Minutes Minutes = (Fraction) × 60 To find how many minutes are in a fraction of an hour, you multiply the fraction by 60, because there are 60 minutes in one whole hour. Fraction of a Minute to Seconds Seconds = (Fraction) × 60 To find how many seconds are in a fraction of a minute, you multiply the fraction by 60, because there are 60 seconds in one whole minute. Finding the Fraction of an Hour Fraction = Number of Minutes / 60 To find what fraction of an hour a certain number of minutes is, create a fraction with the minutes on top (numerator) and 60 on the bottom (denominator). Then, simplify the fraction if you can.
