Explanation of Solution
Given:
At high school 3 out of 8 students are athletes and there are total 1280 students in the school.
Concept Used:
Rules of Addition/ Subtraction:
- Two numbers with similar sign always get added and the resulting number will carry the similar sign.
- Two numbers with opposite signs always get subtracted and the resulting number will carry the sign of larger number.
Rules of Multiplication/ Division:
- The product/quotient of two similar sign numbers is always positive.
- The product/quotient of two numbers with opposite signs is always negative.
Calculation:
In order to find the number of students who are not athletes,observe that 3 out of 8 students are athletes. And the total number of students in the school is 1280. So, the number of students who are athletes would be,
So, the number of students who are not athletes would be
Thus,the number ofstudents who are not athletes is
