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?
20/100
80/100
0.20
0.08
what is it?
To find the percentage of Thomas' math homework that he still needs to complete, we can subtract the problems he has finished from the total number of problems and then divide by the total number of problems.
Remaining problems = Total problems - Finished problems = 20 - 4 = 16
Percentage = Remaining problems / Total problems = 16 / 20 = 0.80 or 80/100
So, the correct answer is 80/100.
