Divisibility Rule of 2
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 2.
What is the Divisibility Rule of 2?
The divisibility rule for 2 is a method by which we can find out if a number is divisible by 2 or not without using the division method. Check whether 246 is divisible by 2 with the divisibility rule.
Step 1: Check if the last digit of the number is even. In 246, the last digit is 6, which is even.
Step 2: Since 6 is even, 246 is divisible by 2.
Tips and Tricks for the Divisibility Rule of 2
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 2.
Know the even numbers:
Memorize the even numbers (0, 2, 4, 6, 8) to quickly check divisibility. If the last digit is one of these numbers, then the number is divisible by 2.
Use the rule for all numbers:
The divisibility rule for 2 applies to any whole number, positive or negative, as long as the last digit is even.
Repeat the process for large numbers:
For very large numbers, only the last digit needs to be checked. If it is even, the entire number is divisible by 2.
Verify with division:
Students can use the division method to verify and cross-check their results. This will help them confirm their understanding.
Common Mistakes and How to Avoid Them in the Divisibility Rule of 2
The divisibility rule of 2 helps us quickly check if a given number is divisible by 2, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes that will help you avoid them.
Mistake 1
Not checking the last digit.
Always check the last digit to see if it is even.
Divisibility Rule of 2 Examples
Problem 1
Is the number of apples in a basket, which is 46, divisible by 2?
Yes, 46 is divisible by 2.
Explanation
To determine if 46 is divisible by 2, check the last digit of the number. Since the last digit is 6, which is an even number, 46 is divisible by 2.
Problem 2
A team of 128 students needs to be split into pairs for a dance competition. Can they be divided evenly?
Yes, 128 is divisible by 2.
Explanation
To check if 128 can be divided evenly by 2, look at the last digit. The last digit of 128 is 8, which is even. Therefore, 128 is divisible by 2.
Problem 3
There are 57 chairs arranged in a hall. Can they be grouped into pairs without any left over?
No, 57 is not divisible by 2.
Explanation
To check if 57 is divisible by 2, observe the last digit of the number. The last digit is 7, which is odd. Hence, 57 cannot be divided evenly by 2.
Problem 4
In a deck of 52 playing cards, can the cards be divided into two equal piles?
Yes, 52 is divisible by 2.
Explanation
To determine if 52 can be divided into two equal piles, look at the last digit. The last digit is 2, which is an even number, so 52 is divisible by 2.
Problem 5
A baker made 99 cupcakes. Can they be arranged in pairs without any remaining?
No, 99 is not divisible by 2.
Explanation
To check if 99 is divisible by 2, look at the last digit of the number. The last digit is 9, which is odd, so 99 cannot be divided evenly by 2.
