How to Calculate 42 out of 52 as a Percentage
Divide the numerator by the denominator, then multiply by 100. The result is the percentage score.
Step by step: 42 divided by 52 equals 0.8077 as a decimal. Multiply that by 100 and you get 80.8%. On the standard US plus/minus grading scale, 80.8% is a B- grade, equal to 2.7 GPA on the 4.0 scale.
What 80.8% Means as a B- Grade
Slightly above average. A 2.7 GPA passes every academic good-standing threshold but falls below the 3.0 floor for graduate programs and some employer filters.
At most US colleges and high schools, the minimum passing score is 60%. A score of 80.8% clears that threshold, so 42 out of 52 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.
