Answer:
40%
Step-by-step explanation:
To find the number of students that take art, we need to find the difference between the number of students in the whole grade and the number of students who take art, that is 75 and 45, respectively. The answer to that is 30 students. Next, we find what percent represents the number of students who take art in relation to the total number of students in the grade. This can be represented by the fraction 30/75. When you simplify, you get 0.4 which is also known as 40%. Therefore 40% of the students take art. Hope this helps:)
