If 67 percent are herbivores, then 33 percent are not.
So we are looking for 33 percent of 925.
Now all we have to do is reduce that to a simple form.
We know that the answer will be around 300ish, because a third of1000 is 333. It's always good to have an idea of what you are looking for.
So if I multiply 925 by 33 and divide the answer by 100, I get the percentage you're looking for. I used a calculator, and got 305.
305 animals are carnivores (not herbivores).
