Divisibility Rule of 10
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 10.
What is the Divisibility Rule of 10?
The divisibility rule for 10 is a method by which we can find out if a number is divisible by 10 or not without using the division method. Check whether 230 is divisible by 10 with the divisibility rule.
Step 1: Observe the last digit of the number. In 230, the last digit is 0.
Step 2: If the last digit is 0, then the number is divisible by 10. Therefore, 230 is divisible by 10.
Tips and Tricks for Divisibility Rule of 10
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 10.
Know the last digit:
Ensure the last digit of the number is 0 to quickly check divisibility by 10. If the last digit is 0, the number is divisible by 10.
Use estimation for large numbers:
For large numbers, check the last digit without getting overwhelmed by the entire number. For example, in 19460, the last digit is 0, hence it is divisible by 10.
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 confirm their understanding.
