Good work!
percent_rank() scores everything from 0 - 1 allowing us to generate distributions or percentiles next question
Desired output:
| name | weight | percent |
| Tigger | 3.8 | 0.0 |
| Molly | 4.2 | 9.1 |
| Ashes | 4.5 | 18.2 |
| Charlie | 4.8 | 27.3 |
| Smudge | 4.9 | 36.4 |
| Felix | 5.0 | 45.5 |
| Puss | 5.1 | 54.5 |
| Millie | 5.4 | 63.6 |
| Alfie | 5.5 | 72.7 |
| Misty | 5.7 | 81.8 |
| Oscar | 6.1 | 90.9 |
| Smokey | 6.1 | 90.9 |
select name, weight, percent_rank() over (order by weight) * 100 as percent from cats order by weight
