Glad that the learning is resonating!
A percent is really a ratio that you can easily scale in tandem. 20% means 20 per 100 or 20 to 100 which has a rate of 0.2 of one unit per another. The tricky part that is complex is that it also has the same units of measure which makes it more of a multiplicative comparison, yet scaling in tandem still feels helpful/useful. Complex stuff!
