\r\n Imagine finishing a 15-question quiz and seeing 12\/15<\/strong> at the top of your paper. Did you do well? What percentage is that? And what letter grade does it become?\r\n <\/p>\r\n\r\n

\r\n

\r\n 12 out of 15 is 80%.<\/strong> On a common U.S. plus\/minus grading scale, 80% is a B-<\/strong>. However, the letter grade can vary because schools and teachers may use different grading scales.\r\n <\/p>\r\n <\/div>\r\n\r\n<\/div>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\r\n How Do You Calculate 12\/15 as a Percentage?\r\n <\/h2>\r\n\r\n

\r\n Converting 12 out of 15 to a percentage takes just two steps:\r\n <\/p>\r\n\r\n

\r\n\r\n
\r\n
\r\n STEP 1\r\n <\/div>\r\n

\r\n Divide 12 by 15.<\/strong>
\r\n 12 \u00f7 15 = 0.8\r\n <\/p>\r\n <\/div>\r\n\r\n

\r\n
\r\n STEP 2\r\n <\/div>\r\n

\r\n Multiply by 100.<\/strong>
\r\n 0.8 \u00d7 100 = 80%\r\n <\/p>\r\n <\/div>\r\n\r\n <\/div>\r\n\r\n

\r\n

\r\n So:
\r\n 12\/15 = 0.8 = 80%<\/strong>\r\n <\/p>\r\n <\/div>\r\n\r\n

\r\n

\r\n There is another easy way to see it. The fraction 12\/15 can be simplified by dividing both numbers by 3:\r\n <\/p>\r\n\r\n

\r\n 12\/15 = 4\/5\r\n <\/p>\r\n\r\n

\r\n Since 4\/5 equals 0.8, it also equals 80%<\/strong>.\r\n <\/p>\r\n <\/div>\r\n\r\n<\/div>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\r\n What Grade Is a 12\/15?\r\n <\/h2>\r\n\r\n

\r\n The percentage is always 80%<\/strong>, but the letter grade depends on the grading scale your school or teacher uses.\r\n <\/p>\r\n\r\n

\r\n

\r\n On a common U.S. plus\/minus scale, 80\u201382% is a B-<\/strong>. For example, grading scales published by Johns Hopkins University and several other U.S. institutions place 80\u201382% in the B- range.\r\n <\/p>\r\n <\/div>\r\n\r\n

\r\n

\r\n 12\/15 = 80% = B-<\/strong>\r\n <\/p>\r\n <\/div>\r\n\r\n

\r\n Some schools use a simpler scale in which 80% is a B<\/strong>. That is why it is best to check the grading scale on your syllabus, assignment, or report card before deciding the exact letter grade.\r\n <\/p>\r\n\r\n<\/div>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\r\n What Does 12\/15 Mean on a 15-Question Test?\r\n <\/h2>\r\n\r\n

\r\n If each question is worth the same amount, 12\/15 means you answered 12 questions correctly and missed 3<\/strong>.\r\n <\/p>\r\n\r\n

\r\n Because the test has only 15 questions, each question makes a noticeable difference. One question is worth:\r\n <\/p>\r\n\r\n

\r\n \r\n 1\/15 \u00d7 100 \u2248 6.67%\r\n <\/span>\r\n <\/div>\r\n\r\n

\r\n That means:\r\n <\/p>\r\n\r\n

\r\n \r\n\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n
\r\n Score\r\n <\/th>\r\n \r\n Percentage\r\n <\/th>\r\n <\/tr>\r\n <\/thead>\r\n\r\n
11\/15<\/td>\r\n 73.33%<\/td>\r\n <\/tr>\r\n\r\n
\r\n 12\/15\r\n <\/td>\r\n \r\n 80%\r\n <\/td>\r\n <\/tr>\r\n\r\n
13\/15<\/td>\r\n 86.67%<\/td>\r\n <\/tr>\r\n\r\n
14\/15<\/td>\r\n 93.33%<\/td>\r\n <\/tr>\r\n\r\n
15\/15<\/td>\r\n 100%<\/td>\r\n <\/tr>\r\n <\/tbody>\r\n\r\n <\/table>\r\n <\/div>\r\n\r\n
\r\n

\r\n This also shows why moving from 12\/15 to 13\/15 makes a noticeable difference: one additional correct answer raises the score from 80% to about 86.67%<\/strong>.\r\n <\/p>\r\n <\/div>\r\n\r\n<\/div>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\r\n Is 12 Out of 15 a Good Grade?\r\n <\/h2>\r\n\r\n

\r\n Whether 12\/15 is a good grade depends on your teacher's expectations and grading system, but mathematically it means you earned 80% of the available points<\/strong>.\r\n <\/p>\r\n\r\n
