This is true because all you do is move where the decimal is: 8*0.25=0.08*25 They're both 8*25*0.01 I used to teach calculus, and the number of kids who didn't understand basic fractions made it nearly impossible to teach them calculus. We need to change elementary math education

The number of elementary teachers I know who do not understand basic fractions is greater than 1.

I'm, like, decent at math (first major in college was stats) and this has never, ever occurred to me. but it makes sense -- percentages are just multiplication, which like addition is a commutative operation. so 0.08 x 25 and 0.25 x 8 shake out identically

Same here, I was a math major , it’s a big part of my job now, and I have 2 elementary school kids and this has never occurred to me.
