1. First you do the exponents and the parentheses -numerator and denominator - (basically multiply the numbers) and you answer should look like this; 25 * 4 - 5 * 16 / 20
2. Then, you multiply the numbers, you answer should look like this; 100 - 80 / 20
3. Subtract the numerator; your answer should look like this; 20/20
4. Divide your answer, and you final answer should be; 1
So, you were correct.
