#13/8# hours or #1 5/8# hours.

To determine how much total time George studied must solve

#3/4 + 7/8#

To do this we must multiply the first fraction by the appropriate form of #1# to get these two fractions over a common denominator, in this case #8#:

#(2/2 xx 3/4) + 7/8 ->#

#((2 xx 3)/(2 xx 4)) + 7/8 ->#

#6/8 + 7/8#

We can now add these two fractions because they are over a common denominator:

#(6 + 7)/8#

#13/8#

or

#(8 + 5)/8 ->#

#8/8 + 5/8#

#1 + /58#

#1 5/8#
