If mark missed 3 days out of 30 what is his percentage of time he was in class

Question

If someone  missed 3 days of class out of 30 days what is percentage of days he was there? 

Answer 1

mark was in school 30-3 =27 days.

The question now is What percent is 27 out of 30 or 27/30. Hence 27/30 as a percent is 27/30 x 100 =90%

Answer 2

if mark missed 3 days out of 30, then he missed 1 day out of 10.

Which means he was in class 9 out of 10 days.

As a fraction, this is represented as 9/10.

As a decimal, it is .9

And as a percent, it is 90%

 

Fractions, decimals, and percentages can all be converted from one to the other. 

 

Answer 3

Percent = 100* (Number of Days Mark was in Class)/(Total Class days)

 

Percent = 100*(30-3)/30

 

Percent = 100*27/30

 

Percent = 2700/30

 

Percent = 90%
