the ratio of swimmers to non swimmers in class are 5:2 if there are 35 students in class how many are non swimmers

Given the ratio of swimmers to non-swimmers in the class is 5:2, and there are 35 students in total, we can solve for the number of non-swimmers as follows:

1. Let the number of swimmers be \( 5x \) and the number of non-swimmers be \( 2x \).
2. According to the problem, the total number of students is \( 5x + 2x = 7x \).
3. We know that \( 7x = 35 \).

To find \( x \):
\[
x = \frac{35}{7} = 5
\]

Now, the number of non-swimmers is:
\[
2x = 2 \times 5 = 10
\]

So, there are **10 non-swimmers** in the class.
