Mr. William's class has a higher rate of students with afterschool jobs because 9 over 30 is greater than 8 over 25.
Mr. William's class has a higher rate of students with afterschool jobs because 9 over 30 is less than 8 over 25.
Ms. Talley's class has a higher rate of students with afterschool jobs because 9 over 30 is less than 8 over 25.
Both classes have the same ratio of students with afterschool jobs.

Answer 1

Answer: Ms. Talley's class has a higher rate of students with afterschool jobs because 9 over 30 is less than 8 over 25.

8/25 > 9/30
Their common denominator is 750.

25 x 30 = 750
30 x 25 = 750

Do the same to their numerators.

8 x 30 = 240
9 x 25 = 225

240/750 > 225/750 -> 8/25 > 9/30
