Question

Deborah found that six of the 24 students in her class on a cell phone what is the ratio of students that own a cell phone to students that do not

Answer 1

Students that do own a cellphone . . . . . 6

Students that don't own a cellphone . . .  (24 - 6) = 18

Ratio of (students that do)  to  (students that do not)

         =                8                :                18

         =         1/3 . 

Answer 2

So Deborah found 1/4 of the students had a cell phone and so what is left I think it will be this 4:1
