Answer:

84%

Explanation:

Answer 2

Answer:

The colony decrease by $84$%

Explanation:

Given -

Total population of butterflies before devastation (P) $= 150$

Total Population of butterflies that survived after the devastation $= 24$

Total population of butterflies that did not survived $= P-p$

Substituting the given values in above equation, we get-

Total population of butterflies that did not survived $= 150 -24$

Percentage by which the butterfly colony decreased $= \frac{P-p}{P} * 100\\= \frac{150-24}{150} * 100\\= 84$%
