Answer:D. 40% of the total number of students.
Explanation:
To determine the percentage of students participating in Activity 2, we need to find the fraction of students assigned to Activity 2 and convert it to a percentage.
According to the given information, the fraction of students assigned to Activity 2 is 2/5.
To convert this fraction to a percentage, we can use the following steps:
1. Divide the numerator (2) by the denominator (5): 2 ÷ 5 = 0.4
2. Multiply the result by 100 to convert it to a percentage: 0.4 × 100 = 40%
Therefore, the number of students participating in Activity 2 is equivalent to 40% of the total number of students.
The correct answer is D. 40% of the total number of students.
