Based on the survey, which park had the greatest percentage of blue butterflies?

Park P
Park Q
Park R
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

=
`(number\ of\ blue\ butterflies\ in\ that\ park)/(total\ butterflies\ in\ that\ park)* 100`

Percentage of blue butterflies in park P

=
`(21)/(82)* 100`

=25.61 %

Percentage of blue butterflies in park Q

=
`(40)/(86)* 100`

=46.51%

Percentage of blue butterflies in park R

=
`(11)/(63)* 100`

=17.46%

Percentage of blue butterflies in park S

=
`(38)/(58)* 100`

=65.52%

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

Park S
