Even numbers are a fundamental concept in mathematics and are integers divisible by 2 without a 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 1 and 400.
Even numbers are numbers that can be divided by 2 evenly without a remainder. All even numbers are multiples of 2. The last digit of even numbers always ends with 0, 2, 4, 6, or 8. There are a total of 200 even numbers ranging from 1 to 400. The even number follows a simple formula of 2n, where n is an integer.
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 1 to 400:
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 from 1 to 400. The even numbers from 1 to 400 are as follows: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, ..., 180, 182, 184, 186, 188, 190, 192, 194, 196, 198, 200, 202, 204, 206, 208, 210, 212, 214, 216, 218, 220, ..., 380, 382, 384, 386, 388, 390, 392, 394, 396, 398, and 400. There are a total of 200 even numbers.
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 200 even numbers, so ‘n’ = 200. Now we can substitute the value of ‘n’. S = 200(200 + 1) S = 200 * 201 = 40,200 Therefore, 40,200 is the sum of all even numbers from 1 to 400. 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, 8 + 20 = 28
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, 166 - 76 = 90 388 - 202 = 186 340 - 90 = 250
Find the sum of even numbers between 10 and 30.
120 is the sum of even numbers between 10 and 30.
As we know, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, and 30 are the even numbers between 10 and 30. Next, we need to calculate the sum of these numbers. 10 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 26 + 28 + 30 = 220 The sum of even numbers from 10 to 30 is 220.
Anna has 60 apples. She wants to divide them equally among her 3 friends. How many apples will each friend get?
Each one gets 20 apples.
There are 60 apples with Anna, and it is an even number. So she has to divide equally among her 3 friends, making it — 60 / 3 = 20, therefore, each friend gets 20 apples.
In a theater, there are 400 seats. Each seat is labeled with a number. All the even-numbered seats are reserved for children. How many even-numbered seats are there?
200 seats.
To find the even-numbered seats in the theater, we divide the total number of seats by 2. Because only the even-numbered seats are reserved for children. 400 / 2 = 200 So, 200 seats are reserved for children in the theater.
John has 12 ducks, 16 dogs, and 8 cats. Each pair of legs makes an even number. How many legs do all the animals have?
136 legs in total.
First, we have to calculate the total number of legs for each type of animal: Ducks have 2 legs, and there are 12 ducks, therefore: 12 * 2 = 24 Dogs have 4 legs, and there are 16 dogs, therefore: 16 * 4 = 64 Cats have 4 legs, and there are 8 cats, therefore: 8 * 4 = 32 Therefore, the total number of legs all the animals have is 24 + 64 + 32 = 120. The animals have 120 legs in total.
There are 386 members in a club. If the members are grouped into sets of 2, how many sets are there?
193 sets.
Grouping into sets of 2 means dividing the total number of people by 2. We need to calculate it as: 386 / 2 = 193. If the people are grouped into sets of 2, there are a total of 193 sets.
Even number: Even numbers are numbers that can be divided by 2 without leaving any remainder. It has a formula of 2n, where n is an integer. The last digit of even numbers always ends in 0, 2, 4, 6, or 8. For example, 222, 346, 400 are some even numbers. Multiple: A number that is a product of multiplying a number by an integer. For instance, 2, 4, 6, 8, etc., are some multiples of 2. These numbers are the result of multiplying 2 by other integers. Remainder: For even numbers, when divided by 2, the remainder is always zero. If we divide a number by another, the leftover value is known as the remainder. Sum: The result of adding numbers. For example, the sum of 2 and 4 is 6. Division: The process of finding how many times one number is contained within another. For example, dividing 10 by 2 results in 5.
