Answer:
4 hours
Step-by-step explanation:
We know that there are 24 hours in a day. Therefore, we will subtract from 24.
If mark spends one-third of his day sleeping, then he will be asleep for 8 hours.
![\frac{1}{3}\times24 \\=\frac{24}{3} \\=8](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%5Ctimes24%20%5C%5C%3D%5Cfrac%7B24%7D%7B3%7D%20%5C%5C%3D8)
We also know that if Mark spends one-sixth of his day at soccer practice, he will have been practicing for 4 hours.
![\frac{1}{6}\times24 \\=\frac{24}{6} \\=4](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D%5Ctimes24%20%5C%5C%3D%5Cfrac%7B24%7D%7B6%7D%20%5C%5C%3D4)
We now simply subtract from 24:
![\text{hours in a day - hours asleep - hours at school - hours practicing} \\24 - 8 - 8 - 4 \\= 4](https://tex.z-dn.net/?f=%5Ctext%7Bhours%20in%20a%20day%20-%20hours%20asleep%20-%20hours%20at%20school%20-%20hours%20practicing%7D%20%5C%5C24%20-%208%20-%208%20-%204%20%5C%5C%3D%204)
Therefore, Mark will have 4 hours of free time.
