Thomas has finished 4 problems of his weekly math homework. If he needs to solve a total of 20 problems, which of the following shows the equivalent of the percentage of his math homework Thomas still needs to complete? A. B. C. D.
To find the percentage of his math homework that Thomas still needs to complete, we can use the formula:
Percentage = (Number of problems remaining / Total number of problems) * 100
Since Thomas has finished 4 problems, the number of problems remaining is 20 - 4 = 16.
So the correct option would be:
C. 80%
