Answer:

3y/ 7

Where y =  the total number of athletes

Step-by-step explanation:

Let the total number of athletes  = y

Let the number of all  baseball athletes = b

Let the number of all  basketball athletes = k

Let the number of all  football athletes  = f

The ratio  b: k : f is given by:

15 : 12 : 8

Total proportion = 15 + 12 + 8

                           =   35

The ratio of all baseball player = 15/ 35

                                                    = 3/7

Number of baseball player =  3/7  of y

                                            = 3y/7

The means the three- seventh ( close to half) of the total athletes play baseball ball.
