To find the percentage of votes in favor of the new speed limit, you can use the formula:
\[ \text{Percentage in favor} = \left( \frac{\text{Number of votes in favor}}{\text{Total number of votes}} \right) \times 100 \]
In this case, the number of votes in favor is 19 and the number of votes opposed is 81. First, we need to calculate the total number of votes:
\[ \text{Total number of votes} = \text{Votes in favor} + \text{Votes opposed} = 19 + 81 = 100 \]
Now, we can plug the values into the percentage formula:
\[ \text{Percentage in favor} = \left( \frac{19}{100} \right) \times 100 \]
Calculating this gives:
\[ \text{Percentage in favor} = 19% \]
Thus, the percentage of the votes that were in favor of the new speed limit is 19%.
