Convert Clock Format 0:15 to Decimal Time Notation

$0:15=$

Let's solve this problem step-by-step:

To determine the result of $0:15$, we recognize that this symbol represents division, with zero as the numerator and fifteen as the denominator.
The operation is thus $0 \div 15$.

Recall the mathematical property related to division: when zero is divided by any non-zero number, the result is always zero. This property is crucial and can be mathematically stated as follows:

• $0 \div a = 0$ for any $a \neq 0$.

In our problem, the denominator is 15, which is clearly a non-zero number. Therefore, we can apply this property directly.

By applying the property:
$0 \div 15 = 0$.

Thus, the calculation leads us to conclude that the value of $0:15$ is indeed:

$0$
