Question

5. The population of koalas in a forest one year ago was 48. In the same forest, one year ago there were 114 snakes. Now there are 40 koalas and 150 snakes. Which

species has experienced the greatest percentage change in population?

Answer 1

The snakes had the greatest percentage change in population.

Explanation:

Koalas: 48 - 40 = 8

What percent is 8 from the original number.

X/100 = 8/48 (cross multiply)

X = (8 * 100)/48 = 16.67%

Snakes:

150 - 114 = 36

X = (/100 * 36)/114 = 31.58 %
