Divisibility by 5:

How do you know that a number is divisible by 5? Well, a number is divisible by 5 if the last digit of a number ends with 5 or 0.

Example 1:

The first thing that we need to do is to inspect the given number if it is divisible by 5 or not.

Since the last digit of a given number is not 5 or 0, then the given number is not divisible by 5. We know that a number ends with 5 or 0 is divisible by 5. There's a remainder of 2 in the division. The answer or a quotient must be a whole number itself. You should not have a fraction or a remainder in the final answer.

Example 2:

The first thing that we need to do is to inspect the given number if it is divisible by 5 or not.

Since the last digit of a given number is 5, then the given number is divisible by 5. There's no remainder or a fraction in the division.

Example 3:

The first thing that we need to do is to inspect the given number if it is divisible by 5 or not.

Since the last digit of a given number is 0, then the given number is divisible by 5. There's no remainder or a fraction in the division.

You should consider in studying the divisibility of a number because you will use these principles later when you will study higher Math subjects that involves the division of a number, simplifying fractions, and even factoring.

This method can also be used for negative integers as long as the last digit is either 5 or 0. Again, there should be no remainder or a fraction in the division.
