In math, multiples are the products we get while multiplying a number with other numbers. Multiples play a key role in construction and design, counting groups of items, sharing resources equally, and managing time effectively. In this topic, we will learn the essential concepts of multiples of 18.
Now, let us learn more about multiples of 18. Multiples of 18 are the numbers you get when you multiply 18 by any whole number, along with zero. Each number has an infinite number of multiples, including a multiple of itself.
In multiplication, a multiple of 18 can be denoted as 18 × n, where ‘n’ represents any whole number (0, 1, 2, 3,…). So, we can summarize that:
Multiple of a number = Number × Any whole number
For example, multiplying 18 × 1 will give us 18 as the product. Multiples of 18 will be larger or equal to 18.
Multiples of 18 include the products of 18 and an integer. Multiples of 18 are divisible by 18 evenly. The first few multiples of 18 are given below:
TABLE OF 18 (1-10) | |
---|---|
18 × 1 = 18 |
18 × 6 = 108 |
18 × 2 = 36 |
18 × 7 = 126 |
18 × 3 = 54 |
18 × 8 = 144 |
18 × 4 = 72 |
18 × 9 = 162 |
18 × 5 = 90 |
18 × 10 = 180 |
TABLE OF 18 (11-20) | |
---|---|
18 × 11 = 198 |
18 × 16 = 288 |
18 × 12 = 216 |
18 × 17 = 306 |
18 × 13 = 234 |
18 × 18 = 324 |
18 × 14 = 252 |
18 × 19 = 342 |
18 × 15 = 270 |
18 × 20 = 360 |
Now, we know the first few multiples of 18. They are 0, 18, 36, 54, 72, 90, 108, 126, 144, 162, 180,...
Understanding the multiples of 18 helps solve mathematical problems and boost our multiplication and division skills. When working with multiples of 18, we need to apply it to different mathematical operations such as addition, subtraction, multiplication, and division.
18, 36, 54, 72, and 90 are the first five multiples of 18. When multiplying 18 from 1 to 5, we get these numbers as the products.
So, the sum of these multiples is:
18 + 36 + 54 + 72 + 90 = 270
When we add the first 5 multiples of 18, the answer will be 270.
While we do subtraction, it improves our comprehension of how the value decreases when each multiple is subtracted from the previous one. 18, 36, 54, 72, and 90 are the first five multiples of 18. So, let us calculate it as given below:
18 - 36 = -18
-18 - 54 = -72
-72 - 72 = -144
-144 - 90 = -234
Hence, the result of subtracting the first 5 multiples of 18 is -234.
To calculate the average, we need to identify the sum of the first 5 multiples of 18, and then divide it by the count, i.e., 5. Because there are 5 multiples presented in the calculation. Averaging helps us to understand the concepts of central tendencies and other values. We know the sum of the first 5 multiples of 18 is 270.
18 + 36 + 54 + 72 + 90 = 270
Next, divide the sum by 5:
270 ÷ 5 = 54
54 is the average of the first 5 multiples of 18.
The product of given numbers is the result of multiplying all of them together. Here, the first 5 multiples of 18 include: 18, 36, 54, 72, and 90. Now, the product of these numbers is:
18 × 36 × 54 × 72 × 90 = 2,550,585,600
The product of the first 5 multiples of 18 is 2,550,585,600.
While we perform division, we get to know how many times 18 can fit into each of the given multiples. 18, 36, 54, 72, and 90 are the first 5 multiples of 18.
18 ÷ 18 = 1
36 ÷ 18 = 2
54 ÷ 18 = 3
72 ÷ 18 = 4
90 ÷ 18 = 5
The results of dividing the first 5 multiples of 18 are: 1, 2, 3, 4, and 5.
