45634
To find out how many students were in class today, we need to add the number of boys and girls in Rosa's class.
Given that there are 15 boys and 12 girls, the total number of students in the class initially is:
15 boys + 12 girls = 27 students
Now, we know that on Wednesday, all the girls were present, which means the number of girls remains the same (12 girls) for that day.
We also know that 1/5 of the boys were absent. To calculate the number of absent boys, we need to find 1/5 of the total number of boys.
1/5 * 15 boys = 3 boys
So, on Wednesday, there were 3 boys absent.
To find the number of students in class today, we subtract the number of absent boys from the initial number of students:
27 students - 3 boys = 24 students
Therefore, there were 24 students in class today.
