Recall the fundamental relationship between degrees and radians: \(180^\circ = \pi\) radians.
To convert an angle from degrees to radians, multiply the degree measure by the conversion factor \(\frac{\pi}{180}\).
Set up the conversion expression for 45 degrees as \(45 \times \frac{\pi}{180}\).
Simplify the fraction if needed, but keep the expression in terms of \(\pi\) to represent radians.
Thus, the expression that converts 45 degrees to radians is \(45 \times \frac{\pi}{180}\).
