Answer 1

Data:

2 of 3 students prefer the company's pencils to their competitor's pencils

high school with 1479 students

Part 1:

You have 1479 students in total and know that 2 of 3 students prefer the company's pencils, then you multiply the toatl number of students by the factor 2/3

`1479\cdot(2)/(3)=(2958)/(3)=986`Then, 986 students in the high school prefer the company's pencils

Part 2:

Of 3 students 1 prefer the pencils of the company's competitorPart 3:

Substract the number of students that prefer the company's pencils from the total of students:

`1479-986=493`Then, 493 students in the high school prefer the pencils of the company's competitorPart 4:

Substract the number of students who prefer the competitor's pencils fom the students that prefer the company's pencils:

`986-493=493`Then, in the high school there are 493 students more that prefer the company's pencils than students who prefer their competitor's pencils
