What grade is 22 out of 40?

To calculate the grade, we need to divide the obtained marks by the total marks and then multiply it by 100 to express the result as a percentage.

Grade = (Obtained marks / Total marks) * 100

Grade = (22 / 40) * 100

Grade = 0.55 * 100

Grade = 55%

Therefore, the grade for obtaining 22 out of 40 is 55%.
