Answer:
14/39 or 35.9%
Step-by-step explanation:
We have a total of 39 students and 14 of which study both Art and Biology
and the rest of the total is unimportant to the question. Since there are 14 students out of 39 we can now do the math and figure out that 14 divied by 39 is right about 35.9 percent.
