Yes, your calculation is correct. To find the number of girls in the classroom, you can use the ratio of boys to girls, which is given as 2:3.
First, you divide the total number of boys (8) by the ratio of boys in the classroom (2).
8 divided by 2 equals 4. This means that for every 2 boys, there is 1 group. In this case, that group contains 4 boys.
To find the number of girls in the classroom, you then multiply the number of groups (which is 4) by the ratio of girls in the classroom (3).
4 multiplied by 3 equals 12. Therefore, there were 12 girls in the classroom.
