I have no clue what your talking about

OpenStudy (amistre64):

spose N = 3.727272.... and therefore 100N = 372.727272... 100N: 372.727272... - N : 3.727272... -------------------- 99 N : 372-3 can we determine N as a fraction with integer parts?

OpenStudy (anonymous):

I guess Yeah.

OpenStudy (amistre64):

N = (369)/(99) therefore N is a rational number ...

OpenStudy (amistre64):

N cant be rational AND irrational at the same time :)
