I guess you have this:
6+%283%2F4%29+%2A5%28+1%2F3%29..........first write a mixed number as a fraction

=%28%286%2A4%2B3%29%2F4%29+%2A%28%285%2A3%2B+1%29%2F3%29.

=%2827%2F4+%29%2A%2816%2F3%29...now multiply nominator by nominator and denominator by denominator

=27%2A16%2F%284%2A3%29

=cross%2827%299%2Across%2816%294%2F%28cross%284%291%2Across%283%291%29

=9%2A4%2F%281%2A1%29

=36
