At the US Naval academy, the ratio of female students to male students is 1:19. If there are 209 female students enrolled, what is the total number of students in the school?

I believe you would multiply 209 by 19, which is 3,971. Correct me if i’m wrong?

Factors of 12
=1, 2, 3, 4, 6, 12
Factors of 12 that add up to numbers
Factors of 12 that add up to 28 =1 + 2 + 3 + 4 + 6 + 12

Factors of 12 that add up to 3 = 1 + 2

Factors of 12 that add up to 6 = 1 + 2 + 3

Factors of 12 that add up to 10 = 1 + 2 + 3 + 4

Factor of 12 in pairs
1 x 12, 2 x 6, 3 x 4, 4 x 3, 6 x 2, 12 x 1
1 and 12 are a factor pair of 12 since 1 x 12= 12

2 and 6 are a factor pair of 12 since 2 x 6= 12

3 and 4 are a factor pair of 12 since 3 x 4= 12

4 and 3 are a factor pair of 12 since 4 x 3= 12

6 and 2 are a factor pair of 12 since 6 x 2= 12

12 and 1 are a factor pair of 12 since 12 x 1= 12
