Simplify the 12/30 to 2/5 (divide numerator and denominator by 6) 2/5 is equivalent to 4/10 or 40%
As a percentage 80%
To find the total number of problems on the test, we can set up the equation based on the percentage score. If 12 problems correct correspond to an 80% score, we can express this as: ( 0.80 \times \text{total problems} = 12 ). Solving for total problems, we get: ( \text{total problems} = \frac{12}{0.80} = 15 ). Therefore, there are 15 problems on the test.
It is: 75%
12 as a percentage of 80 = 100*12/80 = 1200/80 = 15%
66% That's a D.

You missed 12 questions out of 32, which means you got (32-12)=20 questions correct. (20/32) = 0.625; 0.625 * 100 = 62.5. Your percentage is 62.5%.
