To solve this, we can find 1/8 of the dogs and 5/6 of the dogs then add them together. (This is the total amount of brown and black dogs.) Then, we can subtract this number from 96 (total) to find the rest (mixed colors).
1/8 of 96 is 12. There are 12 brown dogs.
5/6 of 96= 96/6*5= 80. There are 80 black dogs.
80+12=92.
Subtract that from 96 and you get 4—the number of dogs with mixed colors.
