Constant variation of (8,6)

Hi my sisters and brothers can tell me the answer because i don’t understand the question

What are the digits that repeat in the smallest sequence of repeating digits in the decimal equivalent of 24/11?

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
