3.11%

Explanation:

To solve percent problems, use the equation a/b=p/100. In this formula, a is the smaller number, b is the larger number, and p is the percent. In this case, a=4, and b=128.6. Plugging these values into the formula, we find:
4/128.6=p/100
Now we can solve the equation for p using cross-multiplication.
4\times100=p\times128.6
400=p\times128.6
p=3.11
So the answer is 3.11%
