10. B, 3/10.
Because if you add all the zombies together, you will get 20 zombies. And there are 6 zombies with the traffic cone on their head, it would be 6/20 which is 3/10.
12. C, 2.
First let's learn what is rage, rage is the biggest number subtract the smallest number.
So if we look at the first group of numbers, the biggest one is 14 and the smallest is 3:
14-3 = 11
Then the second set of numbers, the biggest is 21 and smallest is 12:
21-12= 9
So when we find the difference, we subtract:
11-9 = 2
So the answer is 2.
