It looks like the problem involves converting between degrees and radians. Here's the breakdown of what I see in the image:

1. Converting $\frac{4\pi}{3}$ radians to degrees:

   • The answer is provided as $240^\circ$.

2. Converting $\frac{5\pi}{3}$ radians to degrees:

   • The answer is provided as $300^\circ$.

3. Converting $315^\circ$ to radians:

   • You need to simplify this conversion.

Converting $315^\circ$ to radians:

To convert degrees to radians, use the following formula:

$\text{radians} = \text{degrees} \times \frac{\pi}{180}$

For $315^\circ$:

$315^\circ \times \frac{\pi}{180} = \frac{315\pi}{180} = \frac{7\pi}{4}$

Thus, $315^\circ$ equals $\frac{7\pi}{4}$ radians.

Would you like further details or explanations on these conversions?

Here are 5 related questions you might consider:

1. How do you convert any degree measure to radians?
2. What is the significance of $\pi$ in the context of angle conversion?
3. How would you convert from radians back to degrees?
4. What are the standard angles in radians (like $\frac{\pi}{2}$, $\pi$, etc.)?
5. How do radians relate to the unit circle?

Tip: Always remember that $180^\circ = \pi$ radians, which is key for conversions.
