code:

import math 

tc = int(raw_input()) 

while tc: 
    tc -= 1 
    term = int(raw_input()) 
    row_p = float((-1 + (1 + 8 * term) ** 0.5) / 2.0) 
    row = int(math.ceil(row_p)) 

    pos = term - (row * (row - 1)) / 2; 

    a = row - pos + 1 

    if row % 2 == 0: 
        print 'TERM %d IS %d/%d' % (term, pos, a) 

    else: 
        print 'TERM %d IS %d/%d' % (term, a, pos)
