How do you convert hours into a mixed number?

Answer 1

It may or may not be possible. The answer depends on how many hours and what units you are converting to.

=====

If you are given a decimal amount of hours, just convert like any decimal.

ex: 2.3 hours = 2 3/10 hours

ex: 4.73 hours = 4 73/100 if the fractions will reduce you should do that also

ex: 3.04 hours = 3 4/100 = 3 1/25 hours.

If you are give hours and minutes, since there are 60 min in one hour, 60 becomes the denominator.

Ex: 2 hr 17 min = 2 17/60 hr

Ex: 3 hr 24 min = 3 24/60 = 3 2/5 hr (reduce using 12)

If you have hours, minutes, and seconds ... again minutes as above. But there are 3600 seconds in an hour, so the denominator for seconds is 3600. Then add the two fractions using reducing and the lowest common denominator.

Ex: 3 hr 15 min 20 sec = 3 and (15/60 + 20/3600) = 3 and (1/4 + 1/180)

(LCD = 180) = 3 and (45/180 + 1/180) = 3 46/180 --- reduce

= 3 23/90 hr
