To find the number of boys in the class, we can use the ratio of girls to boys, which is given as 3:2. This means that for every 3 girls, there are 2 boys.
First, we add the parts of the ratio together:
\[
3 + 2 = 5
\]
Next, we can find out how many students each part of the ratio represents by dividing the total number of students by the total parts of the ratio:
\[
\text{Total students} = 35
\]
\[
\text{Value of one part} = \frac{35}{5} = 7
\]
Now, we multiply the number of parts for boys (which is 2) by the value of one part:
\[
\text{Number of boys} = 2 \times 7 = 14
\]
Thus, there are **14 boys** in the class.
