Divisibility Rule of 50
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 50.
What is the Divisibility Rule of 50?
The divisibility rule for 50 is a method by which we can find out if a number is divisible by 50 or not without using the division method. Check whether 350 is divisible by 50 with the divisibility rule.
Step 1: A number must end in two zeros or end with 50 to be divisible by 50. Here in 350, the last two digits are 50.
Step 2: Since the last two digits form the number 50, which is divisible by 50, 350 is divisible by 50.
Tips and Tricks for Divisibility Rule of 50
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 50.
- Know the multiples of 50: Memorize the multiples of 50 (50, 100, 150, 200, etc.) to quickly check divisibility. If the last two digits of a number form a multiple of 50, then the number is divisible by 50.
- Large numbers: For large numbers, just observe the last two digits. If they are 00 or 50, the number is divisible by 50.
- Use the division method to verify: Students can use the division method to verify and crosscheck their results. This will help them verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 50
The divisibility rule of 50 helps us quickly check if a given number is divisible by 50, but common mistakes like calculation errors lead to incorrect conclusions. Here we understand some common mistakes and how to avoid them.
Mistake 1
Not checking the last two digits correctly.
Ensure that only the last two digits are considered to determine if they form 00 or 50.
Mistake 2
Confusing 50 with similar divisibility rules like 5 or 10.
Focus specifically on the rule for 50, which requires the number to end in 00 or 50.
Mistake 3
Overcomplicating the process.
Remember that only the last two digits matter for divisibility by 50.
