To determine which two areas have buckeye and monarch butterflies in the same proportion, we need to calculate the ratio of buckeye butterflies to monarch butterflies for each area. Let's start by calculating these ratios:
1. Area A:
- Buckeye Butterflies: 15
- Monarch Butterflies: 16
- Ratio: [tex]\( \frac{15}{16} = 0.9375 \)[/tex]
2. Area B:
- Buckeye Butterflies: 27
- Monarch Butterflies: 36
- Ratio: [tex]\( \frac{27}{36} = 0.75 \)[/tex]
3. Area C:
- Buckeye Butterflies: 12
- Monarch Butterflies: 25
- Ratio: [tex]\( \frac{12}{25} = 0.48 \)[/tex]
4. Area D:
- Buckeye Butterflies: 24
- Monarch Butterflies: 32
- Ratio: [tex]\( \frac{24}{32} = 0.75 \)[/tex]
5. Area E:
- Buckeye Butterflies: 44
- Monarch Butterflies: 33
- Ratio: [tex]\( \frac{44}{33} \approx 1.3333 \)[/tex]
Now, we compare the ratios to find which areas have the same proportion of buckeye to monarch butterflies:
- Area A: 0.9375
- Area B: 0.75
- Area C: 0.48
- Area D: 0.75
- Area E: 1.3333
We observe that Area B and Area D both have a ratio of 0.75. Therefore, the two areas that have buckeye and monarch butterflies in the same proportion are Area B and Area D.
Hence, the correct answer is:
C. areas B and D
1. Area A:
- Buckeye Butterflies: 15
- Monarch Butterflies: 16
- Ratio: [tex]\( \frac{15}{16} = 0.9375 \)[/tex]
2. Area B:
- Buckeye Butterflies: 27
- Monarch Butterflies: 36
- Ratio: [tex]\( \frac{27}{36} = 0.75 \)[/tex]
3. Area C:
- Buckeye Butterflies: 12
- Monarch Butterflies: 25
- Ratio: [tex]\( \frac{12}{25} = 0.48 \)[/tex]
4. Area D:
- Buckeye Butterflies: 24
- Monarch Butterflies: 32
- Ratio: [tex]\( \frac{24}{32} = 0.75 \)[/tex]
5. Area E:
- Buckeye Butterflies: 44
- Monarch Butterflies: 33
- Ratio: [tex]\( \frac{44}{33} \approx 1.3333 \)[/tex]
Now, we compare the ratios to find which areas have the same proportion of buckeye to monarch butterflies:
- Area A: 0.9375
- Area B: 0.75
- Area C: 0.48
- Area D: 0.75
- Area E: 1.3333
We observe that Area B and Area D both have a ratio of 0.75. Therefore, the two areas that have buckeye and monarch butterflies in the same proportion are Area B and Area D.
Hence, the correct answer is:
C. areas B and D
