Question

Out of 30 problems on the test jose got 4 wrong. What percentage did jose get correct?

Answer 1

Jose got 80% correct 

Answer 2

My answer is 86%.

You take the number you got correct and divide by the number of questions on test.
26 divided by 30 = 0.86666667
Then take that number and multiply it by 100.
0.86666667 times 100 = 86.6666667.
So 86%.
