\end{tabular} & \begin{tabular}{c}
White \\
flowers
\end{tabular} \\
\hline
\begin{tabular}{l}

of plants
\end{tabular} & 669 & 221 \\
\hline
\end{tabular}

What is the ratio of purple flowers to white flowers?

[tex]$\square : 1$[/tex]



Answer :

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].
