Final answer:
Twenty-five percent of students playing musical instruments is equivalent to 1/4 when expressed as a fraction, after simplifying the fraction 25/100.
Step-by-step explanation:
If twenty-five percent of the students played musical instruments, we can express this as a fraction by placing the percentage over 100. Therefore, the fraction of students who played musical instruments would be 25/100, which can be simplified. To simplify, we divide both the numerator and the denominator by their greatest common divisor, which in this case is 25. This simplification gives us 1/4. So, one quarter of the students played musical instruments. To find the fraction of students who played musical instruments, we need to convert the given percentage to a fraction. Since 25% is equivalent to 25 out of 100, the fraction would be 25/100. This fraction can be simplified to 1/4. Therefore, 1/4 of the students played musical instruments.
