25% of students voted for the athlete
Step-by-step explanation:
First you need to know how many students are in total. In this case there is 60, 15+45
Then you write it as a fraction

because 15 voted for athlete out of the 60 students.
After this you need to divide 15÷60 which is . 25 then you transform that number into a percent which is 25%
Rational number, because the Square root of 400 is 20, since 20 x itself is 400. Hope this helps!
