To find the equivalent percentage, we can use the formula: (number of problems completed / total number of problems) * 100%.
In this case, Thomas has finished 4 problems out of a total of 20 problems.
Thus, the equivalent percentage of his math homework that he still needs to complete is: (4 / 20) * 100% = 20%
Therefore, the answer is: A. 20/100.
