86% or B
That would be a grade between 86% and 87%.
100 - 86 = 14.
The grade speaks for itself. If you mean a letter grade, that would depend on the grade-scale which would depend on how hard the test or exercise was. In my grade school that score would have been a "C'. In my college classes, a "B".
86% to 90% is a B plus.
13 ÷ 15 = 0.866666.... or 86 2/3 % which rounds to a grade of 87.
That would be a grade between 86% and 87%.
To calculate the grade, first determine the number of correct answers. If 50 questions were answered and 7 were wrong, then 50 - 7 = 43 questions were correct. The grade can be calculated as (43 correct / 50 total) x 100, which equals 86%. Therefore, the grade is 86%.
86 + 70 = 156 156 / 2 = 78
yes that is horrible
86% of 100 = 86% * 100 = 0.86 * 100 = 86
100 - 86 = 14.

-- Since she answered 86 percent of the questions correctly, she answered the remaining 14 percent of them incorrectly. -- 14% of 100 questions is 14 questions.
It seems like there might be a misunderstanding in your question, but if you're asking about the average of the grades 83, 86, and 86, you can calculate it by adding the grades together (83 + 86 + 86 = 255) and then dividing by the number of grades (3). This gives you an average grade of 85. If you meant something else, please clarify!
I think it's 86%
