There are a few missing information that are pertinent to this problem.

Grade: 3 4 5

Number of science fair projects: 462 759 891

Total number of projects: 462 + 759 + 891 = 2112

99 long tables * 7 projects = 693 projects

2112 - 693 = 1419 projects

1419 projects : 4 projects/short table = 354.75 tables or 355 short tables needed.

total projects: 2112

projects on long table: 693

projects on short table: 1419
