Answer 2

Analysis and Solution

To find the number of students who study only French, we need to subtract the number of students who study both English and French from the total number of students studying French.

Given information: - Total number of students in the class: 34 - Number of students studying English: 25 - Number of students studying both English and French: 18

To find the number of students studying only French, we can use the following formula:

Number of students studying only French = Total number of students studying French - Number of students studying both English and French

Let's calculate it step by step:

1. Total number of students studying French: - We know that every student in the class studies at least one language, either English or French. - The number of students studying English is 25. - Therefore, the number of students studying French can be calculated as: Total number of students - Number of students studying English = 34 - 25 = 9

2. Number of students studying only French: - We know that 18 students study both English and French. - Therefore, the number of students studying only French can be calculated as: Total number of students studying French - Number of students studying both English and French = 9 - 18 = -9

Since the result is negative (-9), it means that there is an error in the given information or the calculation. It is not possible for the number of students studying only French to be negative.

Please double-check the given information and provide any additional details if available.
