Answer:
85%
Step-by-step explanation:
There are two ways to solve this.
1. You can find the percent of birds, and then subtract that from 100%.
To find the percent of birds, divide 45/300 or make the denominator 100 by dividing both parts by 3.
45/300 (as a fraction)
=15/100
That is the same as 15%.
Subtract that from 100% and you get 85%.
2. You find the number of non-bird animals and make that a percent.
300-45=255 non-bird animals
255/300 (as a fraction)
=85/100
That is the same as 85%.
So either way, the answer is 85%.
