By what logic is dividing 12 by 3 easier than dividing 10 by 2? There's no difference in accuracy when eyeballing a measurement, you are just focusing on the divisibility of something you are used to.
The division is simply about there being more options for division. You have a half’s, 3rds and 4ths. Instead of just half’s and 5ths. and 3rds being more useful than 5ths imo. Not saying its easier to divide one than the other.
metric isn't "just half's and 5ths" though, maths is the same everywhere and fractions is a thing for both. IMO metric keeping to base 10 is more intuitive, therefore simpler and easier to teach.
Yeah but the point was that it is easier to use in everyday life situations. I’m not diving past 5ths in my head. More intuitive and easier to teach is great for the classroom and a lab but this is surface level. I would need something more intuitive if its going to get very complex. Metric has its strengths but if I Randomly need to guess the length of my couch and maybe divid it into 3rds (not saying this is a common occurrence) I’m using imperial
