There is #0.6 or 60%# left

Explanation:

Convert hours to minutes.
#1 7/8 hours = 15/8 hours#.

#15/8 hours xx 60 "minutes/hour" = 112.5 "minutes"#.

Since #45# minutes have been watched, there is #(112.5-45)/112.5# of the movie remaining:

#67.5/112.5 =0.6 (60%)# left.

#1 1/8# hours or #1# hour and #7 1/2# minutes

Explanation:

We can give the answer as the remaining time:

#1 7/8 # hours = #1 # hour + #7/8# of an hour

#=60 + 7/8 xx60#

#= 60 + 52.5 = 112.5# minutes

Once #45# minutes of the moves has been watched, there are:

#112.5 -45 = 67.5# minutes left.

This is #1# hour and #7 1/2# minutes.

#45# minutes = #45/60 =3/4# of an hour.

#1 7/8 -3/4# hours

#=1 (7-6)/8 # hours

#= 1 1/8# hours
