1. The problem is to compare the mixed number $3 \frac{1}{8}$ and the percentage $75\%$. 2. First, convert the mixed number $3 \frac{1}{8}$ to an improper fraction or decimal for easier comparison. 3. Convert $3 \frac{1}{8}$: $$3 \frac{1}{8} = 3 + \frac{1}{8} = \frac{24}{8} + \frac{1}{8} = \frac{25}{8} = 3.125$$ 4. Convert $75\%$ to a decimal: $$75\% = \frac{75}{100} = 0.75$$ 5. Now compare $3.125$ and $0.75$. 6. Since $3.125 > 0.75$, the mixed number $3 \frac{1}{8}$ is greater than $75\%$. 7. Final answer: $3 \frac{1}{8} > 75\%$.
