1. State the problem: We need to find 50p as a percentage of 3.64. 2. Convert to the same units: 50p is 4 in pounds, so 50p = 0.50 pounds. 3. Use the percentage formula: $$\text{Percentage} = \left(\frac{\text{part}}{\text{whole}}\right) \times 100$$ Substitute the values: $$\text{Percentage} = \left(\frac{0.50}{4.64}\right) \times 100$$ 4. Calculate the fraction: $$\frac{0.50}{4.64} \approx 0.1077586$$ 5. Multiply by 100 to get the percentage: $$0.1077586 \times 100 = 10.77586$$ 6. Round to two decimal places: $$10.78\%$$ Final Answer: 50p is approximately 10.78% of 4.64.
