Answer

First find out the  how many students participated .

As given

In a survey, a group of students were asked their favorite sport.

Eighteen students chose "other" sports.

Baseball- 40%

Football- 37.5%

Suppose that the total number of students are 100%.

Students play other sports percentage = Total percentage - Baseball percentage -Football percentage

                                                                = 100 - 40 - 37.5

                                                                = 22.5%

Formula

Here Percentage = 22.5%

Part value = 18

Put in the formula

Total value = 80

Therefore the students participated are 80.

Now find out the how many chose football .

Here  Percentage = 37.5%

Total value = 80

Put in the formula

Part value = 30

Therefore the 30 students chose football .
