Divisibility Rule of 25
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 25.
What is the Divisibility Rule of 25?
The divisibility rule for 25 is a method by which we can find out if a number is divisible by 25 or not without using the division method. Check whether 425 is divisible by 25 with the divisibility rule.
Step 1: Check the last two digits of the number. If the last two digits form a number that is divisible by 25, then the entire number is divisible by 25. In 425, the last two digits are 25.
Step 2: Since 25 is divisible by 25, the entire number 425 is divisible by 25.
Tips and Tricks for Divisibility Rule of 25
Learn the divisibility rule to help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 25.
- Know the multiples of 25: Memorize the multiples of 25 (25, 50, 75, 100, 125…etc.) to quickly check divisibility. If the last two digits of a number form a multiple of 25, then the number is divisible by 25.
- Consider the number's end: If a number ends in 00, 25, 50, or 75, it is divisible by 25.
- Repeat the process for large numbers: Students can apply this rule to any large number by only considering the last two digits. For example, check if 3425 is divisible by 25. The last two digits are 25, which is divisible by 25, so 3425 is divisible by 25.
- 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 to verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 25
The divisibility rule of 25 helps us to quickly check if a given number is divisible by 25, but common mistakes like calculation errors lead to incorrect results. Here we will understand some common mistakes and how to avoid them.
Mistake 1
Not checking the last two digits.
Students should focus on the last two digits of the number to determine divisibility by 25.
Divisibility Rule of 25 Examples
Problem 1
Is 4500 divisible by 25?
Yes, 4500 is divisible by 25.
Explanation
According to the divisibility rule of 25, a number is divisible by 25 if its last two digits are either 00, 25, 50, or 75. In this case, the last two digits of 4500 are 00, which means that 4500 is divisible by 25.
Problem 2
Check the divisibility rule of 25 for 3725.
Yes, 3725 is divisible by 25.
Explanation
To determine if 3725 is divisible by 25, we look at the last two digits. The last two digits are 25, which is one of the divisors of 25. Therefore, 3725 is divisible by 25.
Problem 3
Is 1987 divisible by 25?
No, 1987 is not divisible by 25.
Explanation
To check divisibility by 25, we examine the last two digits of the number. The last two digits of 1987 are 87, which is not 00, 25, 50, or 75. Therefore, 1987 is not divisible by 25.
Problem 4
Can 6450 be divisible by 25 following the divisibility rule?
Yes, 6450 is divisible by 25.
Explanation
According to the rule, a number is divisible by 25 if the last two digits are 00, 25, 50, or 75. The last two digits of 6450 are 50, confirming that 6450 is divisible by 25.
Problem 5
Check the divisibility rule of 25 for 9325.
Yes, 9325 is divisible by 25.
Explanation
By the divisibility rule of 25, we only need to look at the last two digits of the number. The last two digits of 9325 are 25, which means it is divisible by 25.
