Calculating the Number of Students Not Studying English

To find out how many students in the class do not study English, we can use the information provided in the search results.

According to the search results, there are 21 students in the class, and 5 out of 7 students study English. Let's calculate the number of students who do not study English based on this information.

Using the information from the search results: 1. 15 - 6 = 9 students study English. 2. 11 - 6 = 5 students do not study English.

Therefore, 5 out of the 21 students do not study English.

This calculation is based on the provided information and the subtraction of the number of students studying English from the total number of students in the class [[2 #]].

Conclusion

Out of the 21 students in the class, 5 students do not study English.
