1. **State the problem:** Simplify the fractions $\frac{0}{18}$, $\frac{18}{18}$, and $\frac{18}{1}$.\n\n2. **Recall the rules:**\n- Any fraction with numerator 0 is 0, i.e., $\frac{0}{n} = 0$ for $n \neq 0$.\n- Any fraction with numerator and denominator equal is 1, i.e., $\frac{n}{n} = 1$ for $n \neq 0$.\n- Any fraction with denominator 1 is the numerator itself, i.e., $\frac{n}{1} = n$.\n\n3. **Simplify each fraction:**\n- $\frac{0}{18} = 0$ because numerator is zero.\n- $\frac{18}{18} = 1$ because numerator equals denominator.\n- $\frac{18}{1} = 18$ because denominator is one.\n\n4. **Final answers:**\n$$\frac{0}{18} = 0, \quad \frac{18}{18} = 1, \quad \frac{18}{1} = 18.$$
