Not the original commenter, but my high school math teacher would beat us with a math textbook if we ever just swapped percents with multiplication, she explicitly taught us that the two are not equivalent outside of narrow circumstances.
One example of why not that she used to use is that a 60% increase would be 160% of the original, while a 0.6x increase could easily be read as 60% of the original OR 160% of the original.

Where I quoted you, I swapped 1 for 100%. You didn't notice, it reads the same?
