To find the percentage of patents that were accepted, you can use the following formula:
\[ \text{Percentage accepted} = \left( \frac{\text{Number of accepted patents}}{\text{Total number of patents applied for}} \right) \times 100 \]
Substituting the values:
\[ \text{Percentage accepted} = \left( \frac{325,979}{629,647} \right) \times 100 \]
Calculating the division first:
\[ \frac{325,979}{629,647} \approx 0.517 \]
Now, multiply by 100 to convert to a percentage:
\[ 0.517 \times 100 \approx 51.7 \]
So, rounding to the nearest tenth of a percent, approximately 51.7% of the patents were accepted.
