To find the percentage of patents that were accepted, you can use the formula:
\[ \text{Percentage} = \left(\frac{\text{Number of accepted patents}}{\text{Total number of patents applied for}}\right) \times 100 \]
Plugging in the numbers:
\[ \text{Percentage} = \left(\frac{325,979}{629,647}\right) \times 100 \]
Calculating the fraction:
\[ \frac{325,979}{629,647} \approx 0.517 \]
Now, multiply by 100 to convert it to a percentage:
\[ 0.517 \times 100 \approx 51.7% \]
To the nearest tenth of a percent, the percentage of patents that were accepted is 51.7%.
