What is the ratio of purple flowers to white flowers?

Sagot :

To determine the ratio of purple flowers to white flowers, we follow these steps:

1. Identify the number of purple flowers and white flowers from the given data:
- Number of purple flowers: 669
- Number of white flowers: 221

2. Calculate the ratio of purple flowers to white flowers by dividing the number of purple flowers by the number of white flowers:
[tex]\[ \text{Ratio of purple flowers to white flowers} = \frac{\text{Number of purple flowers}}{\text{Number of white flowers}} \][/tex]

3. Substitute the given numbers into the formula:
[tex]\[ \text{Ratio of purple flowers to white flowers} = \frac{669}{221} \][/tex]

4. Perform the division:
[tex]\[ \frac{669}{221} \approx 3.0271493212669682 \][/tex]

Therefore, the ratio of purple flowers to white flowers is approximately 3.027 to 1. This means there are about 3.027 purple flowers for every white flower.
