To determine the ratio of purple flowers to white flowers based on the results of the scientist's experiment, we will follow these steps:
1. Identify the number of plants with purple flowers and white flowers.
- The number of plants with purple flowers is 669.
- The number of plants with white flowers is 221.
2. Calculate the ratio of purple flowers to white flowers.
- The ratio can be calculated by dividing the number of purple flowers by the number of white flowers.
[tex]\[
\text{Ratio} = \frac{\text{Number of purple flowers}}{\text{Number of white flowers}} = \frac{669}{221}
\][/tex]
3. Evaluate the division to obtain the ratio.
- Performing the division:
[tex]\[
\frac{669}{221} = 3.0271493212669682
\][/tex]
Thus, the ratio of purple flowers to white flowers is approximately [tex]\( 3.0271493212669682 : 1 \)[/tex].
This ratio indicates that for every 1 white flower, there are about 3.03 purple flowers.
