What is the 80% of 40 marks?

Use this test mark to percentage calculator to easily calculate the percentage given one or more test grades (marks) and the maximum possible number of marks. If you enter marks from multiple test exams or test tasks, they will be summed before the percentage calculation. Suitable for all school and college level exams.

To find the percentage of marks only basic arithmetics with proportions is required. If it is a single mark, first divide the mark by the maximum possible mark and then multiply by 100 to get the percentage. If there are multiple marks involved, first find their sum total, then proceed as if it is a single mark and divide by the maximum total marks out of which these marks were obtained. Multiply by one hundred at the end to convert to percent. You can do this by hand, following the formulae below, or by using our mark percentage calculator above.

For example, if an exam has a single section and the maximum score is 25, for a student who scored 18 enter 18 in the first input field and 25 in the second, then click "Calculate". If an exam has three sections, or a student is scored on three separate subjects, enter the three obtained scores separated by spaces or commas like so "80 60 90" and then enter the maximum score they could have obtained, e.g. 300 if the score ceiling on each test is 100.

Marks to percentage formula

In the simplest case we have just a single exam and therefore a single test grade to work with. In this case the calculation to convert marks into percentage is straightforward by following this formula:

Mark Percentage = Scored Mark / Test Maximum x 100

"Test maximum" corresponds to the "Out of ... marks" input field in our test grade percentage calculator.

If an exam is scored in separate test sections, or if you are calculating the percentage from several separate exams, then the following formula is applicable:

Mark Percentage = Sum of Scored Marks / Test(s) Maximum x 100

The sum is calculated in the usual way using simple algebra. Our calculator handles that for you automatically.

Test marks to percentage - practical examples

First, a simple example with a single test. Let's say a student scored 85 on an exam with a maximum mark of 100. Plugging the numbers into the above formula, we get:

85 / 100 = 0.85 x 100 = 85% so the test percentage is 85%.

Now for a more complicated example where there are two tests or two test sections that are being scored. If a student scored 92 points on the first exam and 88 points on the second one, and the total marks they can get on both tests is 200, what is the percentage that the student scored? To calculate this, we first sum up the two marks and then apply the equation as usual:

(92 + 88) / 200 x 100 = 180 / 200 x 100 = 0.90 x 100 = 90% so the overall percentage mark is 90%.

The table below shows the test grades on a given examination and their corresponding percentages assuming a maximum mark of 200.

Mark percentages with a maximum test score of 200

Marks on test	Marks percentage
20	10%
40	20%
60	30%
80	40%
100	50%
120	60%
140	70%
160	80%
180	90%
200	100%

All test percentages in the table are computed using this exam percentage calculator.

The above method can be expanded to any number of marks, including calculations for the percentage scored by a whole class of students on a given test material, or even across class subjects which can be useful to educators as a measure of success. For example, with 20 students in a class, enter the 20 marks obtained in the "Scored" calculator field (separate by spaces or commas) and then the maximum possible score (e.g. 20x40 = 800 if each student can get a maximum of 40 points) in the "Out of" field.

80% of 40 is 32

Working out 80% of 40

Write 80% as 80/100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
80/100 of 40 = 80/100 × 40
Therefore, the answer is 32
If you are using a calculator, simply enter 80÷100×40 which will give you 32 as the answer.
