73% or C

10/13 right = 77% grade
an f 50% and below is an f 50% to 60% is a d 70% to 80% is a c 80% to 90% is a b 90% and above is an A 13/55 on a calculator do 13 divided by 55 and get 0.236363636 and you get your percent of 24%

if the bearing of the correct a nswer is the same as the o nes that is missed the n % rate of correct a nswers: = (13- 3)/13 * 100% = 10/13 * 100% = 76.92%
You use division. For example 13/47 is approximately 0.276 or 28%. 100-28 is 72 so the grade would be a 72.

You would most likely count each question as one point and then calculate the percentage. For example, if one were to get 9 question right out of 13, it would be 9/13, or 9 ÷ 13. This comes out to be about 69%, or a D+.
That would be a grade between 86% and 87%.
13/14 which is 92.9% approx.
13 ÷ 15 = 0.866666.... or 86 2/3 % which rounds to a grade of 87.
