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 15.
Now, let us learn more about multiples of 15. Multiples of 15 are the numbers you get when you multiply 15 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 15 can be denoted as 15 × 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 15 × 1 will give us 15 as the product. Multiples of 15 will be larger or equal to 15.
Multiples of 15 include the products of 15 and an integer. Multiples of 15 are divisible by 15 evenly. The first few multiples of 15 are given below:
TABLE OF 15 (1-10) | |
---|---|
15 x 1 = 15 |
15 x 6 = 90 |
15 x 2 = 30 |
15 x 7 = 105 |
15 x 3 = 45 |
15 x 8 = 120 |
15 x 4 = 60 |
15 x 9 = 135 |
15 x 5 = 75 |
15 x 10 = 150 |
TABLE OF 15 (11-20) | |
---|---|
15 x 11 = 165 |
15 x 16 = 240 |
15 x 12 = 180 |
15 x 17 = 255 |
15 x 13 = 195 |
15 x 18 = 270 |
15 x 14 = 210 |
15 x 19 = 285 |
15 x 15 = 225 |
15 x 20 = 300 |
Now, we know the first few multiples of 15. They are 0, 15, 30, 45, 60, 75, 90, 105, 120, 135, 150,...
Understanding the multiples of 15 helps solve mathematical problems and boost our multiplication and division skills. When working with multiples of 15, we need to apply it to different mathematical operations such as addition, subtraction, multiplication, and division.
15, 30, 45, 60, and 75 are the first five multiples of 15. When multiplying 15 from 1 to 5 we get these numbers as the products.
So, the sum of these multiples is:
15 + 30 + 45 + 60 + 75 = 225
When we add the first 5 multiples of 15, the answer will be 225.
While we do subtraction, it improves our comprehension of how the value decreases when each multiple is subtracted from the previous one. 15, 30, 45, 60, and 75 are the first five multiples of 15. So, let us calculate it as given below:
15 - 30 = -15
-15 - 45 = -60
-60 - 60 = -120
-120 - 75 = -195
Hence, the result of subtracting the first 5 multiples of 15 is -195.
To calculate the average, we need to identify the sum of the first 5 multiples of 15, 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 15 is 225.
15 + 30 + 45 + 60 + 75 = 225
Next, divide the sum by 5:
225 ÷ 5 = 45
45 is the average of the first 5 multiples of 15.
The product of given numbers is the result of multiplying all of them together. Here, the first 5 multiples of 15 include: 15, 30, 45, 60, and 75. Now, the product of these numbers is:
15 × 30 × 45 × 60 × 75 = 45,562,500
The product of the first 5 multiples of 15 is 45,562,500.
While we perform division, we get to know how many times 15 can fit into each of the given multiples. 15, 30, 45, 60, and 75 are the first 5 multiples of 15.
15 ÷ 15 = 1
30 ÷ 15 = 2
45 ÷ 15 = 3
60 ÷ 15 = 4
75 ÷ 15 = 5
The results of dividing the first 5 multiples of 15 are: 1, 2, 3, 4, and 5.
