Every 15 students who run track

There are 210 students running track and 98 students that play baseball.

Step-by-step explanation:

For every 15 students who run track there are

7 students who play baseball

There are 112 more students who run track

than play baseball

Let y represent the various groups of students

15 × y= 15y

7 × y= 7y

15y - 7y = 112

8y = 112

Divide both side by the coefficient of y which is 8

8y/8 = 112/8

y= 14

Therefore the number of students that run track is

= 15 × 14

= 210

The number of student that play baseball is

= 7 × 14

= 98

Hence 210 students run track and 98 students play baseball
