Even numbers are a fundamental concept in mathematics, representing 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 300 and 400.
Even numbers are the numbers that can be divided by 2 evenly without a remainder. All even numbers are multiples of 2, and they always end with 0, 2, 4, 6, or 8. There are 51 even numbers ranging from 300 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 visual aids that help 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 300 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 300 to 400. The even numbers from 300 to 400 are as follows: 300, 302, 304, 306, 308, 310, 312, 314, 316, 318, 320, 322, 324, 326, 328, 330, 332, 334, 336, 338, 340, 342, 344, 346, 348, 350, 352, 354, 356, 358, 360, 362, 364, 366, 368, 370, 372, 374, 376, 378, 380, 382, 384, 386, 388, 390, 392, 394, 396, 398, and 400. There are a total of 51 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 51 even numbers, so ‘n’ = 51. Now we can substitute the value of ‘n’. S = 51(51 + 1) S = 51 × 52 = 2,652 Therefore, 2,652 is the sum of all even numbers from 300 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, 304 + 316 = 620
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, 386 - 320 = 66 398 - 312 = 86 400 - 350 = 50
Find the sum of even numbers between 310 and 320.
The sum of even numbers between 310 and 320 is 930.
As we know, 310, 312, 314, 316, 318, and 320 are the even numbers between 310 and 320. Next, we need to calculate the sum of these numbers. 310 + 312 + 314 + 316 + 318 + 320 = 1,890 The sum of even numbers from 310 to 320 is 1,890.
A farmer has 60 apples. He wants to divide them equally between his 2 baskets. How many apples will each basket have?
Each basket will have 30 apples.
There are 60 apples, and it is an even number. So he has to divide them equally between his 2 baskets, making it 60 ÷ 2 = 30. Therefore, each basket will have 30 apples.
In a parking lot, there are 200 cars. Each spot is labeled with a number. All the even-numbered spots are reserved for electric cars. How many even-numbered spots are there?
There are 100 even-numbered spots.
To find the even-numbered spots in the parking lot, we divide the total number of spots by 2, because only the even-numbered spots are reserved for electric cars. 200 ÷ 2 = 100 So, 100 spots are reserved for electric cars in the parking lot.
Emma has 12 dogs, 16 cats, and 8 rabbits. Each pair of legs makes an even number. How many legs do all the animals have?
There are 144 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 12 dogs, therefore: 12 × 4 = 48 Cats have 4 legs, and there are 16 cats, therefore: 16 × 4 = 64 Rabbits have 4 legs, and there are 8 rabbits, therefore: 8 × 4 = 32 Therefore, the total number of legs all the animals have is 48 + 64 + 32 = 144. The animals have 144 legs in total.
There are 406 books on a shelf. If the books are grouped into sets of 2, how many sets are there?
There are 203 sets.
Grouping into sets of 2 means dividing the total number of books by 2. We need to calculate it as: 406 ÷ 2 = 203. If the books are grouped into sets of 2, there are a total of 203 sets.
Even number: Even numbers are numbers that are divided by 2 without leaving any remainder. They have 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, 300, 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 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 together. For example, the sum of the even numbers 300 and 302 is 602. Integer: A whole number that can be positive, negative, or zero. Even numbers are integers that are divisible by 2.
