    This is the third time this year that I have come across this. I am pissed that it was never taught in school… and that apparently I keep forgetting it every time.

      A way to remember it is to remember why that’s the case

      8% of 50 = (0.01 • 8) • 50 = 8 • (0.01 • 50) = 50% of 8

      It all just boils down to the fact that multiplication is associative and commutative (aka u can multiply numbers in any order you want)

      Ask me if you have any questions (im a math tutor i love teaching math) 😊

        Also, if you have any tricks for teaching percentages, ratios and basic statistics PLEASE SHARE. My partner has a new job and while he shines at the field work aspect, he has trouble with the mathier parts. He’s had godawful terrible teachers his whole life. I’ve tried coaching him in math but my methods don’t click with him. We also don’t have the time to wade through dozens of YouTube videos hoping to hit the holy grail…

          Yeah in my experience watching youtube videos passively is a waste of time. Time is better spent struggling with math practice problems and guiding him theough it when he’s stuck :-)
