Options:a. Leave out the fifth. b. take notes in the right hand depending on how full you want the chord to sound (careful about doubling certaing tones)c. Leave out the root playing E, Bb, and D. This is good if you have a bass player.d. Use "shell voicings" in left hand also if the tempo is quick. meaning root and 7th or root and third.Hope that helps
Generally, 9th chords are in root position. Can you redistribute to put some of the notes in the RH with the melody? What chord tone is the melody? If you're going to leave out a note, generally only the 5th can be left out without compromising the chord quality.
