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 225.
The divisibility rule for 225 is a method by which we can find out if a number is divisible by 225 or not without using the division method. Check whether 2025 is divisible by 225 using the divisibility rule.
Step 1: Check divisibility by 25. The last two digits of 2025 are 25, which is divisible by 25.
Step 2: Check divisibility by 9. Add the digits of the number: 2+0+2+5=9. Since 9 is divisible by 9, proceed to Step 3.
Step 3: Since 2025 is divisible by both 25 and 9, it is divisible by 225.
Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 225.
Memorize the multiples of 225 (225, 450, 675, 900, ...etc.) to quickly check the divisibility. If a number is divisible by both 25 and 9, it is divisible by 225.
For checking divisibility by 9, sum the digits of the number. If the result is a multiple of 9, the original number is divisible by 9.
For divisibility by 25, ensure the last two digits are either 00, 25, 50, or 75.
Students should keep repeating the divisibility process for each component (25 and 9) until they confirm divisibility for large numbers.
Students can use the division method as a way to verify and crosscheck their results. This will help them verify and also learn.
