1. The problem is to express the fraction 28 over 3 as a mixed number or decimal. 2. The fraction is given as $\frac{28}{3}$. 3. To convert an improper fraction to a mixed number, divide the numerator by the denominator. 4. Divide 28 by 3: $$28 \div 3 = 9 \text{ remainder } 1$$ 5. This means $\frac{28}{3} = 9 \frac{1}{3}$. 6. Alternatively, as a decimal, divide 28 by 3: $$28 \div 3 = 9.333\ldots$$ or $9.\overline{3}$. 7. So, $\frac{28}{3}$ equals the mixed number $9 \frac{1}{3}$ or the decimal $9.\overline{3}$.
