WOW now that you mention it I realize that I didn't really pay attention to it. The Japanese teacher helping me, when he taught me classifiers never put 分 in the H sound examples.
Pushed by Mesaeguさん I went back and check the section where he taught me the dates and time....that's the minutes part.
*minutes(classifier:fun/pun)
ip-pun(一分), ni-fun(二分), san-pun(三分), yon-pun(四分), go-fun(五分), rop-pun(六分)
nana-fun(七分), hap-pun(八分), kyuu-fun(九分), jup-pun(十分), juuip-pun(十一分), juuni-fun(十二分),,,,
I guess I had completely overlooked at it...thinking I already knew how to form the "3 minutes" form.
Thank you for pointing it out.
EDIT. I guess sometimes going back and re-read what we already give for granted wouldn't be a mistake. Lesson learnt
