Working with the given percentages, we will get:
Here we need to work with percentages.
Let's say that X is last year's attendance. We know that 270 is the 125% of last year's attendance, then we will have the relation:
X*(125%/100%) = 270
X*1.25 = 270
X = 270/1.25 = 216
This means that last year's attendance was of 216 people.
The 25% of that is:
216*(25%/100%) = 216*(0.25) = 54
then we can complete the 3 blanks as:
125% of last year's attendance = 270
25% of last year's attendance = 54
100% of last year's attendance = 216
