**Step 1. Convert the arena fraction to a decimal.**

The arena is given as  
$$
\frac{12}{100},
$$  
which as a decimal is  
$$
0.12.
$$

**Step 2. Find the fraction that was not the arena.**

Since the entire colosseum represents the whole or 1 (which can be written as $$\frac{100}{100}$$), the part that was not the arena is the remainder when the arena fraction is subtracted from 1:

$$
\frac{100}{100} - \frac{12}{100} = \frac{100-12}{100} = \frac{88}{100}.
$$

Thus, the fraction of the colosseum that was not the arena is  
$$
\frac{88}{100}.
$$

**Step 3. Write and solve the required equation.**

We are to solve for $$\mathrm{n}$$ in the equation:

$$
\frac{\square}{100} - \frac{\square}{100} = \mathrm{n} : \mathrm{n}=\square.
$$

Replace the blanks with the appropriate numbers:

$$
\frac{100}{100} - \frac{12}{100} = \mathrm{n}.
$$

Performing the subtraction gives:

$$
\mathrm{n} = \frac{100 - 12}{100} = \frac{88}{100}.
$$

**Final Answers:**

- The arena as a decimal is $$0.12$$.
- The fraction that was not the arena is $$\frac{88}{100}$$.
The arena is 0.12 of the colosseum. The part that was not the arena is 88 out of 100, which is $$\frac{88}{100}$$.
