    Given that l ast week christi spent 2 3/4 hours playing piano this week she spent 3 2/4 hours playing the piano, the extra time spent on piano this week will be:

    3 2/4-2 3/4

    Converting the above into proper fraction we get:

    14/4-11/4

    = (14-11) / 4

    =3/4

    Thus she spent and extra 3/4 hours=45 minutes this week
