# Tulane has a ratio of 3 girls to 4 boys in class. If there are 12 girls in class how many total students are there?

$28$

#### Explanation:

$\text{G" : "B} = 3 : 4$

From above ratio of girls and boys we can say that girls ($\text{G}$) are $\frac{3}{7}$ of total ($\text{T}$) and boys are $\frac{4}{7}$ of total.

$\text{G" = 3/7 × "T}$

12 = 3/7 × "T"

"T" = (12 × 7)/(3) = 28

∴ There are total $28$ students in the class.
