See a solution process below:

First, we can write #5 1/4" hours"# as #(5" hours" + 1/4" hours")#

So, first we can add the #5" hours"# to 7:00 PM giving:

#7:00" PM" + 5 = 12:00" AM"#

If #1" hour" = 60" minutes"# then we can divide each side of the equation by #color(red)(4)# to find out how many minutes in a #1/4# of an hour:

#(1" hour")/color(red)(4) = 60/color(red)(4)" minutes"#

#1/4" hour" = 15" minutes"#

We can now add the 15 minutes to the result we had from the previous step giving:

#12:00" AM" + 15" minutes" = 12:15" AM"#
