Answer:
The students who have a cell phone and can use social media are 3.
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:
![(1)/(5)\ of\ 30.](https://img.qammunity.org/2021/formulas/mathematics/middle-school/do2gxa5fq8r3m9w8hgmgl84sb43xxgwp94.png)
![=(1)/(5) * 30.](https://img.qammunity.org/2021/formulas/mathematics/middle-school/42cdalowku6glxxxphf1wdfmpx5ry96fgg.png)
![=(30)/(5)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/8whgad2t8o8ilwrb5we87xos04z640s7gq.png)
![=6.](https://img.qammunity.org/2021/formulas/mathematics/middle-school/785go4m2whjou5gp8g39izye1qs7ye00tk.png)
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:
![(1)/(2)\ of\ 6.](https://img.qammunity.org/2021/formulas/mathematics/middle-school/1ajzaq8cmf6nquxuu5d4uqk7pf11hgjo7c.png)
![=(1)/(2) * 6](https://img.qammunity.org/2021/formulas/mathematics/middle-school/cy35zkh6zdrd1hhg22j7ho592kguj6weir.png)
![=(6)/(2)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/vjljhnuixuqy9fxtqvzd2ice2mv1vmz0ni.png)
![=3.](https://img.qammunity.org/2021/formulas/mathematics/middle-school/pmsl0y3geaon7q45rb95dimfgt1ffmbif5.png)
Therefore, the students who have a cell phone and can use social media are 3.
