Its 1:3

it is 1:3 :p

To find the ratio of boys to total students, we first need to determine the number of boys and girls in the class.

Let's assume the number of boys in the class is B. Since Mr. Kole has twice as many girls as boys, the number of girls would be 2B.

According to the given information, Mr. Kole has 30 students in total. So we can write an equation based on the number of boys and girls:

B + 2B = 30

Combining like terms, we have:

3B = 30

To solve for B, we divide both sides of the equation by 3:

B = 30 / 3
B = 10

Therefore, there are 10 boys in the class. Since we know the total number of students is 30, we can find the number of girls:

Number of girls = 2B = 2 * 10 = 20

Now, we can calculate the ratio of boys to total students:

Boys : Total students = 10 : 30

To simplify the ratio, we can divide both terms by the greatest common factor, which is 10:

10 / 10 : 30 / 10
1 : 3

Therefore, the ratio of boys to total students is 1:3.

20 girls + 10 boys = 30 students

Can you see now which ratio is correct?

boys:total = ?:?
