How To Calculate 13 out Of 15 As a Percentage?

Step 1: Set up the fraction

The first step is to represent the score as a fraction. You have 13 out of 15, so the fraction is 13/15.

The top number (numerator) is the score you achieved, and the bottom number (denominator) is the total possible score.

Step 2: Convert the fraction to a decimal

To turn a fraction into a decimal, you divide the numerator by the denominator. So, you divide 13 by 15.

13 ÷ 15 = 0.866666…

Notice that the 6 repeats. This is a repeating decimal.

Step 3: Round the decimal (if necessary)

Since we’re dealing with percentages, it’s usually best to round to two decimal places. Look at the third decimal place.

If it’s 5 or more, you round the second decimal place up. If it’s less than 5, you leave the second decimal place as it is.

In our case, the third decimal place is a 6, so we round the second 6 up to a 7.

Therefore, the decimal rounded to two places is 0.867.

Step 4: Multiply by 100 to get the percentage

To convert a decimal to a percentage, you multiply by 100.

0.867 x 100 = 86.7%

So, 13 out of 15 is equal to 86.7%.

Step 5: Determine the letter grade

Now, let’s look at your grading system to see what letter grade corresponds to 86.7%.

• B 84–86.99%

Since 86.7% falls within the 84–86.99% range, a score of 13 out of 15 earns a B.
