Divisibility Rule of 100
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 100.
What is the Divisibility Rule of 100?
The divisibility rule for 100 is a method by which we can find out if a number is divisible by 100 or not without using the division method. Check whether 2300 is divisible by 100 with the divisibility rule.
Step 1: Check the last two digits of the number. In 2300, the last two digits are 00.
Step 2: If the last two digits of the number are 00, then the number is divisible by 100. Therefore, 2300 is divisible by 100.
