Answer for screen readers
The percentage of students present today is ( 80% ).
Steps to Solve
-
Calculate the number of students present First, find out how many students are present by subtracting the number of students on leave from the total number of students. $$ \text{Students Present} = \text{Total Students} - \text{Students on Leave} $$ Substituting the known values: $$ \text{Students Present} = 720 - 144 $$
-
Compute the number of students present Calculate the result of the subtraction. $$ \text{Students Present} = 576 $$
-
Calculate the percentage of students present Now, find the percentage of students present using the formula: $$ \text{Percentage} = \left(\frac{\text{Students Present}}{\text{Total Students}}\right) \times 100 $$ Substituting the known values: $$ \text{Percentage} = \left(\frac{576}{720}\right) \times 100 $$
-
Calculate the final result Compute the percentage. $$ \text{Percentage} = \left(0.8\right) \times 100 = 80% $$
The percentage of students present today is ( 80% ).
