How to Calculate 18 out of 24 as a Percentage
Divide the numerator by the denominator, then multiply by 100. The result is the percentage score.
Step by step: 18 divided by 24 equals 0.75 as a decimal. Multiply that by 100 and you get 75.0%. On the standard US plus/minus grading scale, 75.0% is a C grade, equal to 2.0 GPA on the 4.0 scale.
What 75.0% Means as a C Grade
Average. A 2.0 GPA is the minimum for most academic good-standing policies. Scores at this level risk ineligibility for Dean's List and selective programs.
At most US colleges and high schools, the minimum passing score is 60%. A score of 75.0% clears that threshold, so 18 out of 24 is a passing grade. Always verify with your institution, as some programs require a C or higher (70%) for courses that count toward major requirements.
