Answer:
21 male students
Explanation:
For every teacher on the trip, 3 male students and 5 female students are there
If there are 35 female students, we have to divide that by 5 to find the number of teachers
35 divided by 5 is 7
There are seven teachers, so we multiply by 3 to find the number of male students
7 x 3 = 21
There are 21 male students on the school field trip
