Find the Missing Operator: Solve 360 ? 360 = 1

To determine which sign makes the expression true, we will evaluate each arithmetic operation between $360$ and $360$ to see which gives a result of $1$.

• Step 1: Consider addition: $360 + 360 = 720$, which is not equal to $1$.
• Step 2: Consider subtraction: $360 - 360 = 0$, which is not equal to $1$.
• Step 3: Consider multiplication: $360 \times 360 = 129600$, which is also not equal to $1$.
• Step 4: Consider division: $\frac{360}{360} = 1$

Among these operations, only division satisfies the condition $360 \text{?} 360 = 1$ as $\frac{360}{360} = 1$.

Therefore, the correct operation is division, represented by the symbol :.
