the ratio of girls to boys is 3:5 .If there are 15 boys in the classroom ,how many students are there total
Cross multiply and solve for t.
15/t = 5/8
To determine the total number of students in the classroom, we need to find the ratio of girls to boys and use the information given.
The ratio of girls to boys is given as 3:5. This means that for every 3 girls, there are 5 boys.
We know that there are 15 boys in the classroom. Since the ratio of girls to boys is 3:5, we can set up the following proportion:
3 girls / 5 boys = x girls / 15 boys
To solve for x, we can cross-multiply:
(3 girls)(15 boys) = (5 boys)(x girls)
45 girls = 5x girls
Dividing both sides by 5:
45 girls / 5 = x girls
9 girls = x girls
Therefore, there are 9 girls in the classroom.
To find the total number of students, we add the number of girls and boys:
Total number of students = Number of girls + Number of boys
Total number of students = 9 girls + 15 boys
Total number of students = 24 students
So, there are a total of 24 students in the classroom.
