Advance Topics

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 20.

What are the Multiples of 20?

Now, let us learn more about multiples of 20. Multiples of 20 are the numbers you get when you multiply 20 by any whole number, including zero. Each number has an infinite number of multiples, including a multiple of itself. In multiplication, a multiple of 20 can be denoted as 20 × 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 20 × 1 will give us 20 as the product. Multiples of 20 will be larger or equal to 20.Multiples of 20

List of First 20 Multiples of 20

Multiples of 20 include the products of 20 and an integer. Multiples of 20 are divisible by 20 evenly. The first few multiples of 20 are given below:

 

TABLE OF 20 (1-10)

20 x 1 = 20

20 x 6 = 120

20 x 2 = 40

20 x 7 = 140

20 x 3 = 60

20 x 8 = 160

20 x 4 = 80

20 x 9 = 180

20 x 5 = 100

20 x 10 = 200

 

TABLE OF 20 (11-20)

20 x 11 = 220

20 x 16 = 320

20 x 12 = 240

20 x 17 = 340

20 x 13 = 260

20 x 18 = 360

20 x 14 = 280

20 x 19 = 380

20 x 15 = 300

20 x 20 = 400

Now, we know the first few multiples of 20. They are 0, 20, 40, 60, 80, 100, 120, 140, 160, 180, 200,...

Operations with Multiples of 20

Understanding the multiples of 20 helps solve mathematical problems and boosts our multiplication and division skills. When working with multiples of 20, we need to apply it to different mathematical operations such as addition, subtraction, multiplication, and division.

 

Sum of first 5 Multiples of 20:


20, 40, 60, 80, and 100 are the first five multiples of 20. When multiplying 20 from 1 to 5, we get these numbers as the products.  
So, the sum of these multiples is:


20 + 40 + 60 + 80 + 100 = 300


When we add the first 5 multiples of 20, the answer will be 300.

 

Subtraction of first 5 Multiples of 20:


While we do subtraction, it improves our comprehension of how the value decreases when each multiple is subtracted from the previous one. 20, 40, 60, 80, and 100 are the first five multiples of 20. So, let us calculate it as given below:


20 - 40 = -20
-20 - 60 = -80
-80 - 80 = -160
-160 - 100 = -260


Hence, the result of subtracting the first 5 multiples of 20 is -260.

 

Average of first 5 Multiples of 20:


To calculate the average, we need to identify the sum of the first 5 multiples of 20, 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 20 is 300.


20 + 40 + 60 + 80 + 100 = 300


Next, divide the sum by 5:


300 ÷ 5 = 60


60 is the average of the first 5 multiples of 20.

 

Product of First 5 Multiples of 20:


The product of given numbers is the result of multiplying all of them together. Here, the first 5 multiples of 20 include: 20, 40, 60, 80, and 100. Now, the product of these numbers is:


20 × 40 × 60 × 80 × 100 = 38,400,000

 

The product of the first 5 multiples of 20 is 38,400,000.

 

Division of First 5 Multiples of 20:

 

While we perform division, we get to know how many times 20 can fit into each of the given multiples. 20, 40, 60, 80, and 100 are the first 5 multiples of 20.


20 ÷ 20 = 1
40 ÷ 20 = 2
60 ÷ 20 = 3
80 ÷ 20 = 4
100 ÷ 20 = 5    

The results of dividing the first 5 multiples of 20 are: 1, 2, 3, 4, and 5.
