To get the number of rows u have to divide the number of boys over the number of girls.
72/90 = 8/10

Given,
Number of boys = 72
Number of girl`s = 90
To Find,
The greatest number of students that can be in each row such that all of the students are in equal rows with only girl`s or only boys in each row=?
Solution,
By factorizing both numbers,
72 = 2 * 2 * 2 * 3 * 3
90 = 2 * 3 * 3 * 5
Common factors of 72 and 90 = 2 * 3 * 3
The greatest common factor of 72 and 90 = 2 * 3 * 3 = 18
Hence, 18 is the greatest number of students that can be in each row such that all of the students are in equal rows with only girl`s or only boys in each row.
