No, the math term ratio doesn't mean multiply.
The common ratio is the ratio of the nth term (n > 1) to the (n-1)th term. For the progression to be geometric, this ratio must be a non-zero constant.
Derived unit
Direct Proportion
The second term in the ratio is 1.
Antecedent is the first term in a ratio .
This term neans a worsening as described in the text

the lowest term of 4 percent in a ratio is 1:25
It is a*r^4 where a is the first term and r is the common ratio (the ratio between a term and the one before it).
The common ratio is the ratio of the nth term (n > 1) to the (n-1)th term. For the progression to be geometric, this ratio must be a non-zero constant.

It could certainly be described as a simple ratio of positive integers.
You start with the number 4, then multiply with the "common ratio" to get the next term. That, in turn, is multiplied by the common ratio to get the next term, etc.
