Divisibility Rule For 15 –The divisibility rule for 15 states that if the sum of the digits of a number is divisible by 3, then the number is divisible by 3. For example, the number 15 is divisible by 3 because the sum of its digits (1+5) is 6, which is divisible by 3.

To know what is the divisibility rule for 15 you are at the right place.

This rule can be used to quickly determine whether a number is divisible by 15 without having to divide the number by 15.

To use the rule, simply check to see if the number is divisible by 3 and 5. If it is, then it is also divisible by 15. For example, let’s check to see if 60 is divisible by 15. We know that 60 is divisible by 3 and 5 (since it’s divisible by both 6 and 12), so we can conclude that it’s also divisible by 15.

This rule can be a helpful tool when working with large numbers since division can be time-consuming. PDF

## Divisibility Rule For 15

The Divisibility Rule For 15 can be a helpful tool for students who are struggling with the division. To use the rule, simply take the last digit of the number in the question and divide it by 3. If the answer is 1, 5, or 9, then the number is divisible by 15.

For example, if a student is trying to determine if the number 45 is divisible by 15, they would take the last digit (5) and divide it by 3. Since 5 divided by 3 equals 1.5, and 1 is one of the numbers listed in the rule, this means that 45 is divisible by 15.

Divisibility rule for fifteen with examples given here:

– 75 is divisible by 15 because it is divisible by both 3 (25) and 5 (15).

– 90 is also divisible by 15 because it is divisible by both 3 (30) and 5 (18).

– 105 is another number that follows the rule because it is divisible by both 3 (35) and 5 (21). PDF

### Examples of Divisibility Rule of 15

For example, the number 45 is divisible by 15 because it is divisible by both 3 (15) and 5 (9).

The rule can be applied to any number that is a multiple of 15. So, for instance, the number 150 is also divisible by 15 because it is a multiple of 15 (10 x 15).

The divisibility rules 15 can be used to quickly determine whether a number is divisible by 15 without having to divide it by 3 and 5 separately. This can be useful when working with large numbers or when trying to save time.

There are several benefits of learning the rules of divisibility for 15  . This rule can help students to more easily understand and work with division problems. It can also help them to better understand other related concepts such as multiplication, fractions, and decimals. Additionally, learning this rule can help students to develop their critical thinking and problem-solving skills.

Divisibility Rules are mathematical properties that tell us when a certain number is divisible by another number. The divisibility rule for 15 is a necessary tool in many lines of work, that involves money or time. PDF

For example, let’s say you’re a cashier and someone hands you a \$50 bill to pay for their \$32.50 purchase. You would need to know the divisibility rule for 15 in order to give them the correct amount of change – in this case, \$17.50.

The same goes for if you’re keeping track of time. If an event is scheduled to start at 7:15 pm, you would need to use the divisibility rule for 15 in order to know that it will start in 15 minutes.
