Answer:
1 : 3
Step-by-step explanation:
Debra found that 6 of the 24 students in her class own a cellphone.
Students who own a cellphone = 6
Students who do not own a cellphone = 24 - 6 = 18
Ratio of the students that own a cell phone to students that do not =
6 : 18 [ simplify it ]
1 : 3
Therefore, the ratio is 1 : 3
