1. The problem is to create a math problem involving the word "sex" as part of a variable or context, not inappropriately. 2. Let's consider a problem involving the number of males and females in a group, where "sex" refers to gender. 3. Problem: In a class, the ratio of males to females (sex ratio) is 3:2. If there are 30 students in total, how many males and females are there? 4. Formula: Let the number of males be $3x$ and females be $2x$. 5. Since total students are 30, we have: $$3x + 2x = 30$$ 6. Simplify: $$5x = 30$$ 7. Solve for $x$: $$x = \frac{30}{5} = 6$$ 8. Calculate number of males: $$3x = 3 \times 6 = 18$$ 9. Calculate number of females: $$2x = 2 \times 6 = 12$$ 10. Answer: There are 18 males and 12 females in the class.
