Question

In a class of 40 students, 12 entered a math competition. What percentage of the class is this?

a) 20%
b) 30%
c) 25%
d) 35%

Answer 1

To find the percentage of students who entered the math competition, divide the number of students who entered the competition by the total number of students in the class and multiply by 100 to get the percentage.

Step-by-step explanation:

To find the percentage of students who entered the math competition, you need to divide the number of students who entered the competition (12) by the total number of students in the class (40). Then, multiply the result by 100 to find the percentage.

In this case, the calculation would be:

12 / 40 * 100 = 0.3 * 100 = 30%

Therefore, the answer is option b) 30%.
