Answer:

3 students

Step-by-step explanation:

There are 30 students in Mrs. Woodward’s class.

[tex]\dfrac{1}{5}[/tex] of the class has their own cell phone, so

[tex]\dfrac{1}{5}\cdot 30=\dfrac{1}{5}\cdot \dfrac{30}{1}=6[/tex]

students have their own cell phones.

[tex]\dfrac{1}{2}[/tex] of those 6 students are allowed to use social media. So,

[tex]\dfrac{1}{2}\cdot 6=\dfrac{1}{2}\cdot \dfrac{6}{1}=3[/tex]

students are allowed to use social media.
