For Ella's grade

The ratio of boys to girls in Ella's grade is 3 to 4. = 3:4

3 + 4 = 7

The number of students is represented as x

Hence,

4/7 × x = 20

4x = 20 × 7

4x = 140

x = 140/4

x = 35 students

The number of boys is

3/7 × 35 = 15 students.

The ratio of boys to girls in Minh's grade is 4 to 5 = 4:5

4 + 5 = 9

The number of students is represented as x

Hence,

5/9 × x = 20

5x= 20 × 9

5x = 180

x = 180/5

x = 36 students

The number of boys is

4/9 × 36 = 16 students.
