If in the first quarter they scored 1/6 of their points, this would mean in the first quarter they scored 6 points (36/6=6). If in the second quarter they scored 1/4 of their points, they scored 9 points (36/4=9). If in the third quarter they scored 1/3 of their points, they scored 12 points (36/3=12).
12+9+6=27.
36 - 27 = 9
the answer is c, 9
