John invited 30 people and 20% didn't show up, so 30 x 0.20 = <<30*0.20=6>>6 people didn't show up.
Therefore, 30 - 6 = <<30-6=24>>24 people showed up to the party.
Of the people who showed up, 75% ordered steak, so 24 x 0.75 = <<24*0.75=18>>18 people ordered steak.
The remaining people, 24 - 18 = <<24-18=6>>6 people, ordered chicken.
Therefore, 6 people ordered chicken.
#### 6
The answer is: 6
