If I had my 'druthers, all percentages would be replaced by multiplication factors. I would especially eradicate percentages combined with modifiers like "more", "less", "grows by", etc., which easily leads to awkward or impossibly ambiguous statements.
In other words, kids won't learn "150% more" but instead "2.5x". Nothing will be described as "shrinks by 30%", it'll just be 0.70x.
While advertisers/marketers may love percentages for tricking people with a Big Happy Number, mathematically they are extra work at best, and sometimes they just ruin everything like this "100% finer" nonsense."
