    First you add both together to find the total number of answers which is 60. You make a fraction of how many correct over total number, getting 42/60. You then simplify it to make it 21/30. If you divide 21/30, you will get. 7. The last step is to take the decimal and move it 2 places back to make it a percentage. It will become 70%, making that your answer.
