Divisibility Rule of 900
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 900.
What is the Divisibility Rule of 900?
The divisibility rule for 900 is a method by which we can find out if a number is divisible by 900 or not without using the division method. Check whether 5400 is divisible by 900 with the divisibility rule.
Step 1: Check if the number is divisible by both 100 and 9, since 900 = 100 × 9.
Step 2: To check divisibility by 100, the last two digits of the number should be 00. In 5400, the last two digits are 00, so it is divisible by 100.
Step 3: To check divisibility by 9, sum the digits of the number. For 5400, 5 + 4 + 0 + 0 = 9. Since 9 is divisible by 9, the number is divisible by 9.
Step 4: Since 5400 is divisible by both 100 and 9, it is divisible by 900.
Tips and Tricks for Divisibility Rule of 900
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 900.
Know the multiples of 900:
Memorize the multiples of 900 (900, 1800, 2700, 3600, etc.) to quickly check divisibility. If the result meets both criteria of divisibility by 100 and 9, then the number is divisible by 900.
Use the digit sum for the divisibility of 9:
If the sum of the digits is a multiple of 9, then the number is divisible by 9.
Repeat the process for large numbers:
Students should keep repeating the divisibility process until they reach a number that is manageable to work with using the divisibility rules for 100 and 9.
Use the division method to verify:
Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn.
