Question
In a school, 45 of the teachers have had their flu vaccine and 27 have not. What is the proportion of teachers who have not had their flu vaccine?
Solution
To find the proportion of teachers who have not had their flu vaccine, follow these steps:
-
First, find the total number of teachers. You do this by adding the number of teachers who have had their flu vaccine to the number of teachers who have not. In this case, that's 45 teachers (who have had their vaccine) + 27 teachers (who have not) = 72 teachers in total.
-
Next, divide the number of teachers who have not had their flu vaccine by the total number of teachers. So, 27 (teachers who have not had their vaccine) ÷ 72 (total teachers) = 0.375.
-
To express this as a percentage, multiply by 100. So, 0.375 x 100 = 37.5%.
So, the proportion of teachers who have not had their flu vaccine is 37.5%.
