Answer:
3rd grade
Explanation:
Given that the values are different types (fractions, decimals, and percentages), it would be helpful to convert them to the same type of value.
Converting everything to percentages seems more convenient.
Since 61.24% is already a percentage, we simply have to convert 0.52, 25/36, and 0.5274444 (I wrote 0.5274 like this since the 4 is a repeating value).
To convert 0.52, we simply multiply by 100:
0.52 * 100 = 52%
For 25/36, we need to know its decimal form and multiply by 100 to find the percentage:
25 / 36 = 0.6944 * 100 = 69.44%
For 0.5274444, we also multiply by 100:
0.5274444 * 100 = 52.74444
Thus, we have 52% (2nd grade), 69.44% (3rd grade), 61.24% (4th grade), and 52.74444% (5th grade).
3rd grade has the highest portion of students
