I'm a bit confused because Brainly says you marked this as an "English" question but it is a math question. The answer is simply 95%. If you're wondering what grammar mistakes the question itself has, just replace the dash mark with a period.
Explanation:
This is a pretty basic fraction to decimal conversion problem. Divide 19 by 20 to the decimal 0.95. The number "1.00" represents 100% when it comes to percentages so 0.95 would be 95%.
