Answer 2

As per the data given in the question,

In the above question, it is given that,

In a school out of 800 student, 20½ % are absent

Here we have to find the number of students present.​

We have to use the percentage of the ratio.

Now considering the ratio of $20\frac{1}{2} \%$ are absent.

The number of students absent is

$=\frac{20\frac{1}{2}}{100}\times 800$

Solving the above equation we get,

$=164 students$

Therefore the number of students present,

$=800-164\\=636 students$

Hence the number of students present is 636 students.
