1. The problem asks: What percent is 4 of 50? 2. To find the percent, we use the proportion formula: $$\frac{\text{part}}{\text{whole}} = \frac{\text{percent}}{100}$$ 3. Substitute the known values: $$\frac{4}{50} = \frac{x}{100}$$ 4. Cross multiply to solve for $x$: $$4 \times 100 = 50 \times x$$ 5. Simplify: $$400 = 50x$$ 6. Divide both sides by 50: $$\frac{400}{\cancel{50}} = \frac{50x}{\cancel{50}}$$ 7. This simplifies to: $$8 = x$$ 8. So, 4 is 8 percent of 50. Final answer: **8%**
