n - 15 < 48 Add '15' to both sides n - 15 + 15 < 48 + 15 n < 63
15/48 = 5/16
15% of $48 = 0.15 x $48= $7.2
32 questions total 15 wrong number right / total= 32-15=17 so.... 17/32 = 0.53125 mulitply it by 100%= about 53% YOU GOT 53%

If you got two wrong out of 15 questions, you would have answered 13 questions correctly. To calculate your grade, you would divide the number of correct answers by the total number of questions and multiply by 100. In this case, (13/15) x 100 = 86.67%. Therefore, your grade would be approximately 86.67%.

48 = 300 1____x If it takes 1 minute to grade 48 then it will take "x" amount of minutes to grade 300. The first fraction has to equal the second fraction when they are cross multiplied together. 1 times 300 has to equal 48x. Divide both by 48 and you will get x = 6.25 minutes (6 and a quarter minutes) which equates to six minutes 15 seconds.
