1. The problem asks to find what percentage 137.55 is of 17,204.59. 2. The formula to find the percentage of a part relative to the whole is: $$\text{Percentage} = \left(\frac{\text{Part}}{\text{Whole}}\right) \times 100$$ 3. Here, the part is 137.55 and the whole is 17,204.59. 4. Substitute the values into the formula: $$\text{Percentage} = \left(\frac{137.55}{17204.59}\right) \times 100$$ 5. Calculate the division: $$\frac{137.55}{17204.59} \approx 0.007995$$ 6. Multiply by 100 to convert to percentage: $$0.007995 \times 100 = 0.7995$$ 7. Therefore, 137.55 is approximately 0.80% of 17,204.59.
