1. The problem asks to translate the phrase "Six fewer than a number" into a mathematical expression. 2. "A number" is usually represented by a variable, commonly $n$. 3. "Six fewer than a number" means you take the number $n$ and subtract 6 from it. 4. The correct symbolic expression is therefore: $$n - 6$$ 5. The other options do not correctly represent "six fewer than a number": - $n < 6$ means "number is less than six". - $6 - n$ means "six minus the number", which is "six fewer than the number" reversed. - $6 < n$ means "six is less than the number". Hence, the correct answer is $n - 6$.
