@gcvsa That has to be some kind of brain-wiring thing - to me, division is never going to be the intuitive approach. I mean, I can usually divide by two, I'm not that dumb, but a system of divison, which switches between at least 8ths & 16ths, will never work as well for me as (essentially) adding integers and/or zeroes. If I just throw out, say, 4/8 and 5/16, I have no concept of the relation between those two - even if I try to think about it I have no idea if they're close or not.
