In a science test, Jamie solved 42 correct and 18 incorrect answers. What is the percentage of correct questions and how did you get it?

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.

Answer:70%
