Answer:

the common ratio is 0.98.

Explanation:

A fish population in a lake decreases by 2% each year. We are asked to find the common ratio.

The decrease of population of fish 2% annually means the population becomes next year 100% - 2% = 98%

Therefore, the common ratio would be 98%. Upon converting 98 percent to a decimal we will get,

98% =
(98)/(100)=0.98

Therefore, the common ratio or decay factor is 0.98.
