Question Analysis

The question asks for a detailed response regarding the number of students participating in a choir club and the proportion of all students involved in choir singing.

Answer:

To solve this problem, we need to use the given information that out of 600 students in the school, 7/12 of them participate in various clubs, and out of those, 2/7 are in the choir club.

a) To find the number of students in the choir club, we can calculate 2/7 of the total number of students participating in clubs.

b) To determine the proportion of all students involved in choir singing, we can calculate the ratio of the number of students in the choir club to the total number of students in the school.

Let's calculate the answers step by step.

Calculation:

a) Number of students in the choir club: To find the number of students in the choir club, we need to calculate 2/7 of the total number of students participating in clubs.

Total number of students participating in clubs = 7/12 * 600 Number of students in the choir club = 2/7 * (7/12 * 600)

b) Proportion of all students involved in choir singing: To determine the proportion of all students involved in choir singing, we need to calculate the ratio of the number of students in the choir club to the total number of students in the school.

Proportion of students involved in choir singing = (Number of students in the choir club) / (Total number of students in the school)

Now, let's calculate the answers using the given information.

Calculation:

a) Number of students in the choir club: Total number of students participating in clubs = 7/12 * 600 = 350 Number of students in the choir club = 2/7 * 350 = 100

b) Proportion of all students involved in choir singing: Proportion of students involved in choir singing = 100 / 600 = 1/6

Answer:

a) The number of students in the choir club is 100. b) The proportion of all students involved in choir singing is 1/6.
