Park S

Answer 1

park s because it 65.5% blue

Answer 2

Answer with Step-by-step explanation:

Percentage of blue butterflies in any park

=$\dfrac{number\ of\ blue\ butterflies\ in\ that\ park}{total\ butterflies\ in\ that\ park}\times 100$

Percentage of blue butterflies in  park P

=$\dfrac{21}{82}\times 100$

=25.61 %

Percentage of blue butterflies in  park Q

=$\dfrac{40}{86}\times 100$

=46.51%

Percentage of blue butterflies in  park R

=$\dfrac{11}{63}\times 100$

=17.46%

Percentage of blue butterflies in  park S

=$\dfrac{38}{58}\times 100$

=65.52%

Hence, park which had the greatest percentage of blue butterflies is:

Park S
