Answer:

PRESENT: 36
ABSENT: 4

Step-by-step explanation:

Write 90% as [tex]\frac{90}{100}[/tex]

Since finding the fraction of a number is the same as multiplying the fraction with the number, we have

[tex]\frac{90}{100}[/tex] of 40 = [tex](\frac{90}{100} ) (40)[/tex]

Therefore, the answer is 36

To find the number of absent students we will just simply subtract the present students by the number of students in the class

[tex]40-36 = 4[/tex]
