Question

Write first five multiples of 9.

Answer 1

Hint:
Here, we need to find the first five multiples of the number 9. When a number is multiplied by a natural number, then the product is called the multiple of the first number. We will multiply the number 9 by the first five natural numbers to find required multiples of 9.

Complete step by step solution:
Multiple of an element or number means the product of the element or number by an integer.
For example: The product of 4 and 6 is 24. Here, 24 is a multiple of both 4 and 6.
We will multiply the number 9 by the first five natural numbers using the concept of multiplication to find the first five multiples of 9.
The first five natural numbers are 1, 2, 3, 4, 5.
The product of 9 and 1 is 9.
The product of 9 and 2 is 18.
The product of 9 and 3 is 27.
The product of 9 and 4 is 36.
The product of 9 and 5 is 45.

Therefore, we get the first five multiples of 9 as 9, 18, 27, 36, and 45.

Note:
We used the term ‘natural numbers’ in the solution. Natural numbers include all the positive integers like 1, 2, 3, etc. For example: 1, 2, 100, 400, 52225, are all natural numbers. The natural numbers are the basic numbers we use when counting objects.
A common mistake is to use whole numbers instead of natural numbers, and write the product of 9 and 0, that is 0, as the first multiple.
Multiplication is the repeated addition of equal groups. It helps in adding multiple equal groups quickly. It is denoted by the symbol \[ \times \]. Brackets may also be used to denote multiplication.
For example: Suppose that the number 2 is added repeatedly 15 times, that is \[2 + 2 + \ldots \ldots + 2\] 15 times. This can be represented using multiplication as \[2 \times 15 = 30\].
