Answer :

Answer:

Mrs Morgan = The part = 36, Mrs Gregory = The whole = 180

Step-by-step explanation:

Mrs Morgan:

The part because they listed the percent and the whole of her athletes.

[tex]\frac{x}{120}[/tex] = [tex]\frac{30}{100}[/tex] You do Cross multiplication and get 36

Therefore, It's 36

Mrs Gregory:

The whole because they listed the percent and the part of her athletes.

[tex]\frac{27}{15}[/tex] = [tex]\frac{x}{100}[/tex] You do cross multiplication and get 180

Therefore it's 180

The number of athletes  in Mrs. Morgan's class is 36.

The number of students in Mr. Gregory's class is 180.

We are to determine the number of students that are athletes in Mrs. Morgan's class. In order to determine the number of athletes in the class, this formula would be used:

Percentage of athletes in the class x total number of students

30% x 120

0.3 x 120 = 36 students

We are to determine the number of students in Mr. Gregory's class given the percentage of athletes and the number of athletes in the class. In order to determine the number o the students in the class, this formula would be used:

Number of students in the class = number of athletes / percentage of athletes

27 / 15%

27 / 0.15 = 180 students
