Answer:
The students who have a cell phone and can use social media are 3.
Step-by-step explanation:
The question is incomplete so the complete question is:
There are 30 students in Mrs. Bailey’s class, and 1/5 of the class has their own cell phone. Of this group of students, 1/2 of them are allowed to use social media. How many of the students have a cell phone and can use social media?
Now, as given in question we need to find the number of students have a cell phone and can use social media.
Now, to get the number of students of the class who has their own cell phone:
[tex]\frac{1}{5}\ of\ 30.[/tex]
[tex]=\frac{1}{5} \times 30.[/tex]
[tex]=\frac{30}{5}[/tex]
[tex]=6.[/tex]
Of this group of 6 students, 1/2 of them are  allowed to use social media.
So, to get the number of students who use social media:
[tex]\frac{1}{2}\ of\ 6.[/tex]
[tex]=\frac{1}{2} \times 6[/tex]
[tex]=\frac{6}{2}[/tex]
[tex]=3.[/tex]
Therefore, the students who have a cell phone and can use social media are 3.
