Divisibility Rule of 5
The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly and sorting things. In this topic, we will learn about the divisibility rule of 5.
What is the Divisibility Rule of 5?
The divisibility rule for 5 is a method by which we can find out if a number is divisible by 5 or not without using the division method. Check whether 205 is divisible by 5 with the divisibility rule.
Step 1: Look at the last digit of the number. Here in 205, the last digit is 5.
Step 2: If the last digit is 0 or 5, then the number is divisible by 5. As the last digit of 205 is 5, the number is divisible by 5.
Tips and Tricks for Divisibility Rule of 5
Learn divisibility rules to help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 5.
Know the multiples of 5:
Memorize the multiples of 5 (5, 10, 15, 20, 25, etc.) to quickly check divisibility. If the number ends in 0 or 5, then it is divisible by 5.
Use the division method to verify:
Students can use the division method as a way to verify and cross check their results. This will help them verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 5
The divisibility rule of 5 helps us to quickly check if the given number is divisible by 5, but common mistakes like calculation errors lead to incorrect results. Here we will understand some common mistakes that will help you to avoid them.
Mistake 1
Not checking the last digit correctly.
Students should ensure they check the last digit of the number. If it is 0 or 5, then the number is divisible by 5.
Mistake 2

Remember that the rule for 5 only involves checking if the last digit is 0 or 5.
Divisibility Rule of 5 Examples
Problem 1
Can the year 2025 be celebrated as a milestone divisible by 5?
Yes, 2025 is divisible by 5.
Explanation
According to the divisibility rule for 5, a number is divisible by 5 if its last digit is either 0 or 5. The year 2025 ends with a 5, so it is divisible by 5.
Problem 2
Is the amount $1,430 evenly divisible among 5 friends?
Yes, $1,430 is divisible by 5.
Explanation
To check if $1,430 is divisible by 5, look at the last digit. The number ends in 0, which satisfies the rule. Therefore, $1,430 can be evenly divided among 5 friends.
Problem 3
Can a sequence of 15-minute intervals fit perfectly into an 85-minute schedule?
No, 85 is not divisible by 5.
Explanation
To determine divisibility by 5, check the last digit of 85. Since the last digit is 5, 85 is divisible by 5, making it possible to divide the schedule into 15-minute intervals evenly. However, if the question is interpreted differently, where 15-minute intervals are considered for another aspect, it would involve further calculation.
Problem 4
