To find the ratio of purple flowers to white flowers in the experiment, we follow these steps:
1. Identify the number of each type of flower:
- Number of purple flowers: \( 669 \)
- Number of white flowers: \( 221 \)
2. Calculate the ratio of purple flowers to white flowers:
- The ratio is found by dividing the number of purple flowers by the number of white flowers.
[tex]\[
\text{Ratio} = \frac{669}{221}
\][/tex]
3. Perform the division to find the value of the ratio:
[tex]\[
\text{Ratio} = 3.0271493212669682
\][/tex]
4. Express the ratio in the form \( X : 1 \):
- Since the ratio \( \frac{669}{221} \) simplifies to approximately \( 3.0271493212669682 \), we can express this as \( 3.0271493212669682 : 1 \).
Therefore, the ratio of purple flowers to white flowers is approximately [tex]\( 3.0271493212669682 : 1 \)[/tex].
