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 200 and 400.
Even numbers are numbers that are divided by 2 evenly without 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 101 even numbers ranging from 200 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 200 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 200 to 400. The even numbers from 200 to 400 are as follows: 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 101 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 101 even numbers, so ‘n’ = 101. Now we can substitute the value of ‘n’. S = 101(101 + 1) S = 101 * 102 = 10,302 Therefore, 10,302 is the sum of all even numbers from 200 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, 208 + 220 = 428.
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, 366 - 276 = 90 398 - 222 = 176 340 - 290 = 50
Find the sum of even numbers between 210 and 220.
430 is the sum of even numbers between 210 and 220.
As we know, 210, 212, 214, 216, 218, and 220 are the even numbers between 210 and 220. Next, we need to calculate the sum of these numbers. 210 + 212 + 214 + 216 + 218 + 220 = 1,290 The sum of even numbers 210 to 220 is 1,290.
Sarah has 80 apples. She wants to divide them equally between her 4 friends. How many apples will each friend get?
Each one gets 20 apples.
There are 80 apples with Sarah, and it is an even number. So she has to divide equally between her 4 friends making it — 80 / 4 = 20, therefore, each friend gets 20 apples.
In a stadium, there are 400 seats. Each seat is labeled with a number. All the even-numbered seats are reserved for special guests. How many even-numbered seats are there?
200 seats.
To find the even-numbered seats in the stadium, we divide the total number of seats by 2. Because only the even-numbered seats are reserved for special guests. 400 / 2 = 200 So, 200 seats are reserved for special guests in the stadium.
John has 15 dogs, 25 cats, and 10 rabbits. Each pair of legs makes an even number. How many legs do all the animals have?
220 legs in total.
First, we have to calculate the total number of legs for each type of animal: Dogs have 4 legs, and there are 15 dogs, therefore: 15 * 4 = 60 Cats have 4 legs and there are 25 cats, therefore: 25 * 4 = 100 Rabbits have 4 legs and there are 10 rabbits, therefore: 10 * 4 = 40 Therefore, the total number of legs all the animals have is 60 + 100 + 40 = 200. The animals have 200 legs in total.
There are 380 people on a bus. If the people are grouped into sets of 2, how many sets are there?
190 sets.
Grouping into sets of 2 means dividing the total number of people by 2. We need to calculate it as: 380 / 2 = 190. If the people are grouped into sets of 2, there are a total of 190 sets.
Even number: Even numbers are numbers that are 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, and 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 the few multiples of 2. These numbers are the result of multiplying 2 by other integers. Remainder: For even numbers, while 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 two or more numbers. For even numbers, the sum of two or more is also an even number. Pairing: The process of grouping items into sets of 2. For even numbers, pairing indicates equal distribution.
