I think there isn't an outlier because 22 is close to 17 and 4 is close to 5 and 6. Please let me know if I'm wrong.

4 is even!
-22
22-17=5 5+6=11 11-3=8 8/2=4
5
17+5=22 17-5= 12
17 + 5 = 22 17 - 5 = 12

2m-5=17 +5=+5 ___ 22 Therefore, 2m = 22 22 / 2 = 11 m = 11

(5 and one over two) x (seventeen over twenty two) is (5 and 1/2) x (17/22) and is (11/2) x (17/22) which is 17/4 = 4 and 1/4
