You can put this solution on YOUR website!
His rate = ( number of decks built ) / ( his time to build them )
His unit rate = ( 1 deck built ) / ( his time to build 1 deck )
-------------------------
given:
+%28%28+3%2F4+%29%29+%2F+%28%28+9%2F2+%29%29+ decks/days
----------------------------------
Multiply top and bottom by +4%2F3+

+1+%2F%28+%28%28+4%2F3+%29%29%2A%28%28+9%2F2+%29%29+%29+
+1+%2F+6+
The unit rate is 6 days to build 1 deck
