1 and 1/4 hours could be written as 1.25 hours (1/4 is 0.25 in decimal form)
there is 60 minutes in 1 hour, so:
(1.25 hours) x 60 minutes/1 hour= ?minutes
the unit hour is cancelled, then multiply 1.25 to 60 which will give you an answer of 75 minutes
so, just add 75 minutes and 5 minutes (for they have the same unit now that makes it possible to combine them)
therefore, 1 and 1/4 hours and 5 minutes is equivalent to 80 minutes

1/4 hour is 15 minutes
5 minutes is 5 minutes
so 60+15+5 = 80

Since there are 60 minutes in an hour, 1.25*60=75 minutes; add another 5 minutes to this and you have 80 minutes.
