I'm pretty sure its 40% but I'm just double checking

Answer:
Wrong, it's 36% but nice try
Step-by-step explanation:
10 dogs
9 cats
4 hamsters
2 birds
25 pets
9 cats out of 25 pets
9 / 25 × 100
0.36 × 100
= 36%
40% is close but I think that there was a mistake in adding up the different numbers.

36%
