Remember that when posting questions here, you have to write the complete question in order to get a great and correct answer. Anyway, I found the complete question and is as follows:
<em>A grading machine can grade 96 multiple-choice tests in 2 minute. How long will it take the machine to grade 300 tests?</em>
<em />
So this problem can be used by using proportions. So we have that a grading machine can grade 96 multiple-choice tests in 2 minute. So we need to find the time (t) it takes the machine to grade 300 tests. So:
<em>Hence, it would take the machine 6.25 minutes, that is, 6 minutes and 15 seconds to grade 300 tests.</em>
