To determine if 25,445 is divisible by 5, let's focus on the properties of numbers that allow us to check for divisibility by 5. A key piece of knowledge here is that a number is divisible by 5 if its last digit is either 0 or 5.
Here’s the step-by-step explanation:
1. Identify the last digit of the given number. In this case, the number is 25,445.
2. Look at the last digit of 25,445, which is 5.
3. Since the last digit is 5, we apply the rule for divisibility by 5: a number ending in 0 or 5 is divisible by 5.
Since the last digit of 25,445 is 5, we conclude that 25,445 is indeed divisible by 5. This rule ensures that without having to perform any division, we can determine the divisibility by inspecting the last digit alone.
