To determine the percentage of farmers who prefer producing carrots and have rocky soil, we need to calculate the relative frequency of farmers with rocky soil who prefer carrots.

From the data provided:

  • Number of farmers with rocky soil who prefer carrots: 100
  • Total number of farmers who prefer carrots: 220

Now we can calculate the relative frequency:

\[ \text{Relative frequency} = \frac{\text{Number of farmers with rocky soil who prefer carrots}}{\text{Total number of farmers who prefer carrots}} = \frac{100}{220} \]

Calculating that fraction:

\[ \frac{100}{220} \approx 0.4545 \]

To convert this to a percentage:

\[ 0.4545 \times 100 \approx 45.45% \]

Rounding to the nearest tenth gives us:

\[ 45.5% \]

Therefore, the answer is 45.5%.
