Answer 1

Answer:

A number whose unit digit is 5 is always a multiple of 5

Answer 2

The number will be a multiple of 5

Given : The number has 5 as its unit digit.

To find : The number of which the said number is a multiple.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to determine the required number)

Here, we have to apply the 'divisibility by 5 rule'.

Divisibility by 5 rule :

• A number is said to be divisible by 5, when its unit digit is either 5 or 0. Eg. 10,15 etc.

Now, the said number also has 5 as its unit digit. So, it will be divisible by 5 and will be a multiple of 5 as well.

Hence, the number will be a multiple of 5
