There is $0.6 or 60 %$ $0.6 or 60%$ left

Convert hours to minutes.
$1 \frac{7}{8} h o u r s = \frac{15}{8} h o u r s$ $1 7/8 hours = 15/8 hours$ .

$\frac{15}{8} h o u r s \times 60 minutes/hour = 112.5 minutes$ $15/8 hours xx 60 "minutes/hour" = 112.5 "minutes"$ .

Since $45$ $45$ minutes have been watched, there is $\frac{112.5 - 45}{112.5}$ $(112.5-45)/112.5$ of the movie remaining:

$\frac{67.5}{112.5} = 0.6 (60 %)$ $67.5/112.5 =0.6 (60%)$ left.

$1 \frac{1}{8}$ $1 1/8$ hours or $1$ $1$ hour and $7 \frac{1}{2}$ $7 1/2$ minutes

We can give the answer as the remaining time:

$1 \frac{7}{8}$ $1 7/8$ hours = $1$ $1$ hour + $\frac{7}{8}$ $7/8$ of an hour

$= 60 + \frac{7}{8} \times 60$ $=60 + 7/8 xx60$

$= 60 + 52.5 = 112.5$ $= 60 + 52.5 = 112.5$ minutes

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

$112.5 - 45 = 67.5$ $112.5 -45 = 67.5$ minutes left.

This is $1$ $1$ hour and $7 \frac{1}{2}$ $7 1/2$ minutes.

$45$ $45$ minutes = $\frac{45}{60} = \frac{3}{4}$ $45/60 =3/4$ of an hour.

$1 \frac{7}{8} - \frac{3}{4}$ $1 7/8 -3/4$ hours

$= 1 \frac{7 - 6}{8}$ $=1 (7-6)/8$ hours

$= 1 \frac{1}{8}$ $= 1 1/8$ hours
