Question

If 27 of the 36 students of a class were present on a certain day, What percentage of the students were absent on certain day?

Answer 1

Answer:

Given:-

27 out of 36 were present

that is 36-27=9 students were absent

Solution:-

we've to find the absent percentage, we've got 9 students absent

thus to find ,what % of 36 is 9

using

$\frac{9}{36} \times 100 \\ \frac{1}{4} \times 100 \\ \frac{100}{4} \\ = 25$

therfore 25% of the total students were absent

Let's check whether it's correct or not

$\frac{25}{100} \times 36 = 9 \\ \frac{900}{100} = 9 \\ 9 = 9$

L.H.S=R.H.S

hence verified
