Answer:
Step-by-step explanation:
On pet day 18 children brought a pet to school.
2/3 of the pets were dogs. This means that the number of pets that were dogs would be
2/3 × 18 = 12 dogs
1/9 of the pets were cats. This means that the number of pets that were cats would be
1/9 × 18 = 2 dogs
Total number of dogs and cats is
12 + 2 = 14
The number of animals that were neither dogs nor cats is
18 - 14 = 4
