There is $0.6 or 60%$ left

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

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
