The common ratio of the set of data is 0. 1
<h3>How to determine the common ratio</h3>
To determine the common ratio of a set of data, we have to
- Divide the second term by the first term or
- Divide the third term by the second term
For the given set of data
0.1,0.01,0.001
Let's divide the second term by the first term
= 0. 01/ 0. 1
= 0. 1
Thus, the common ratio of the set of data is 0. 1
