It’s not wrong, it’s close enough. And the point it works with more numbers and more type of calculation. Let’s calculate 4% of 1243. That’s the same as 1243% of 4, right, much easier to calculate by simply changing the 2 numbers… While my method is the same, by simply rounding everything.
And in engineering you always multiply/divide your results by a 1.5 or 1.25 safety factor, depending on situation. So you don’t have to calculate exact results, just close enough. E.g. G is always 10m/s2. π is only 3.14, the other digits doesn’t matter.
Huh? It’s not “close enough”, it’s exactly accurate. 4% of 75 is 3 exactly. I don’t know where the rest of what you wrote comes from. This post is about pure arithmetic

That’s the stupidest shit I have heard today. You should feel ashamed if you really are an engineer
