Even Numbers 20 to 40
Even numbers are a fundamental concept in mathematics and they are integers divisible by 2 without remainder. Even numbers play a significant role in organizing data, architecture, pairing, and grouping items equally. In this topic, we will learn about even numbers between 20 and 40.
Even Numbers 20 to 40
Even numbers are the numbers that are divided by 2 evenly without remainder. All numbers are even multiples of 2. The last digit of even numbers always ends with 0, 2, 4, 6, or 8. There are a total of 11 even numbers ranging from 20 to 40. The even number follows a simple formula of 2n, where n is an integer.
Even Numbers 20 to 40 Chart
Learning about even numbers can be made easier with a visual aid that helps children grasp the concept more effectively. A chart allows them to recognize the sequence of even numbers more clearly. Here’s a list of even numbers from 20 to 40:
List of Even Numbers 20 to 40
Even numbers are expressed in the form of ‘n = 2k’. Here, ‘k’ is an integer, and ‘n’ is the number. These numbers are divisible by 2 and the remainder equals zero. Now, let us list the even numbers 20 to 40. The even numbers from 20 to 40 are as follows: 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, and 40. There are a total of 11 even numbers.
Sum of Even Numbers 20 to 40
To find the sum of even numbers, the formula is - S = n(n+1), where ‘n’ is the count of even numbers, and ‘S’ is the sum. There are a total of 11 even numbers, so ‘n’ = 11. Now we can substitute the value of ‘n’. S = 11(11 + 1) S = 11 × 12 = 132 Therefore, 132 is the sum of all even numbers from 20 to 40. If we add an even number to an even number, the answer will always be an even number. Even numbers are multiples of 2. The sum of two multiples of 2 is also another multiple of 2; therefore, it is always an even number. For example, 24 + 30 = 54.
Subtraction of Even Numbers 20 to 40
Subtraction of even numbers involves subtracting each even number from the next. Each even number is uniformly spaced by 2. If we subtract two even numbers, it gives an even number as the result. For example, 36 - 24 = 12 40 - 22 = 18 28 - 20 = 8
Even Numbers 20 to 40 Examples
Problem 1
Find the sum of even numbers between 24 and 34.
144 is the sum of even numbers between 24 and 34.
Explanation
As we know, 24, 26, 28, 30, 32, and 34 are the even numbers between 24 and 34. Next, we need to calculate the sum of these numbers. 24 + 26 + 28 + 30 + 32 + 34 = 174 The sum of even numbers 24 to 34 is 174.
Problem 2
Emma has 40 apples. She wants to divide them equally between her 2 friends. How many apples will each friend get?
Each one gets 20 apples.
Explanation
There are 40 apples with Emma, and it is an even number. So she has to divide equally between her 2 friends making it — 40 ÷ 2 = 20, therefore, each friend gets 20 apples.
Problem 3
In a concert hall, there are 40 seats. Each seat is labeled with a number. All the even-numbered seats are reserved for VIPs. How many even-numbered seats are there?
20 seats.
Explanation
To find the even-numbered seats in the concert hall, we divide the total number of seats by 2. Because only the even-numbered seats are reserved for VIPs. 40 ÷ 2 = 20 So, 20 seats are reserved for VIPs in the concert hall.
Problem 4
Liam has 5 dogs, 3 cats, and 2 rabbits. Each pair of legs makes an even number. How many legs do all the animals have?
40 legs in total.
Explanation
First, we have to calculate the total number of legs for each type of animal: Dogs have 4 legs, and there are 5 dogs, therefore: 5 × 4 = 20 Cats have 4 legs, and there are 3 cats, therefore: 3 × 4 = 12 Rabbits have 4 legs, and there are 2 rabbits, therefore, 2 × 4 = 8 Therefore, the total number of legs all the animals have is 20 + 12 + 8 = 40. The animals have 40 legs in total.
Problem 5
There are 38 people on a bus. If the people are grouped into sets of 2, how many sets are there?
19 sets.
Explanation
Grouping into sets of 2 means dividing the total number of people by 2. We need to calculate it as: 38 ÷ 2 = 19. If the people are grouped into sets of 2, there are a total of 19 sets.
