A percentage is a fraction multiplied by 100. That's all you need to know, anything else is confusion.

"Difference" means difference. That means 2264 - 1888. Whatever that works out to, I can't find my calculator and I find arithmetic demeaning.
"percentage" is "fraction times 100".
So "percentage difference" is "fraction(al) difference times 100".
The "fraction(al) difference" is the difference expressed as a fraction.
Fraction of what??? Good question! Fraction of the first or of the second number? I believe in this context that it's the fraction of the first number.
So the "fractional difference" is (2264 - 1888) / 2264 which if you work it out with a calculator you probably get something like 0.17 or something.
Then the "percentage difference" is that number times 100. Which ought to get you to your 17%.
