1. The problem is to simplify the fraction $\frac{\delta}{16}$. 2. To simplify a fraction, we divide the numerator and denominator by their greatest common divisor (GCD). 3. Since $\delta$ is a variable and 16 is a constant, the fraction is already in simplest form unless $\delta$ shares a factor with 16. 4. Without additional information about $\delta$, the simplest form remains $\frac{\delta}{16}$. Final answer: $\frac{\delta}{16}$
