Even numbers are a fundamental concept in mathematics, being integers divisible by 2 without remainder. They play a significant role in organizing data, architecture, pairing, and grouping items equally. In this topic, we will explore even numbers between 50 and 100.
Even numbers are those divisible by 2 evenly, without remainder. They end with 0, 2, 4, 6, or 8. In the range from 50 to 100, there are 26 even numbers. These numbers follow the simple formula 2n, where n is an integer.
Learning about even numbers is easier with a visual aid that helps grasp the concept more effectively. A chart allows recognition of the sequence of even numbers clearly. Here’s a list of even numbers from 50 to 100:
Even numbers can be expressed as ‘n = 2k’, where ‘k’ is an integer and ‘n’ is the number. These numbers are divisible by 2, with a remainder of zero. Let us list the even numbers from 50 to 100: 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, and 100. There are a total of 26 even numbers.
To find the sum of even numbers, use the formula - S = n(n+1), where ‘n’ is the count of even numbers, and ‘S’ is the sum. With 26 even numbers, ‘n’ = 26. Now substitute the value of ‘n’: S = 26(26 + 1) S = 26 * 27 = 702 Therefore, 702 is the sum of all even numbers from 50 to 100. Adding two even numbers always results in an even number, as even numbers are multiples of 2. For example, 54 + 60 = 114.
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, the result is also an even number. For example, 86 - 76 = 10 98 - 50 = 48 100 - 60 = 40
Find the sum of even numbers between 60 and 70.
130 is the sum of even numbers between 60 and 70.
The even numbers between 60 and 70 are 60, 62, 64, 66, 68, and 70. Calculating their sum gives: 60 + 62 + 64 + 66 + 68 + 70 = 130 Thus, the sum of even numbers from 60 to 70 is 130.
Anna has 30 apples. She wants to divide them equally between her 3 friends. How many apples will each friend get?
Each one gets 10 apples.
Anna has 30 apples, and this is an even number. Dividing equally among her 3 friends: 30 / 3 = 10 Thus, each friend gets 10 apples.
In a hall, there are 100 chairs. All the even-numbered chairs are reserved for guests. How many even-numbered chairs are there?
50 chairs.
To find the number of even-numbered chairs, divide the total number of chairs by 2, as only even-numbered chairs are reserved: 100 / 2 = 50 So, 50 chairs are reserved for guests.
Mark has 8 dogs, 12 cats, and 4 parrots. Each pair of legs makes an even number. How many legs do all the animals have?
88 legs in total.
Calculating the total number of legs for each type of animal gives: Dogs have 4 legs, and there are 8 dogs: 8 * 4 = 32 Cats have 4 legs, and there are 12 cats: 12 * 4 = 48 Parrots have 2 legs, and there are 4 parrots: 4 * 2 = 8 Thus, the total number of legs is 32 + 48 + 8 = 88. The animals have 88 legs in total.
There are 72 students in a class. If the students are grouped into sets of 2, how many sets are there?
36 sets.
Grouping into sets of 2 means dividing the total number of students by 2: 72 / 2 = 36 If the students are grouped into sets of 2, there are a total of 36 sets.
Even number: Even numbers are numbers divisible by 2 without leaving any remainder. They follow the formula 2n, where n is an integer. The last digit of even numbers is always 0, 2, 4, 6, or 8. For example, 54, 76, 100. Multiple: A number that is the product of multiplying a number by an integer. For instance, 50, 52, 54, etc., are multiples of 2. Remainder: When an even number is divided by 2, the remainder is always zero. The leftover value after division is known as the remainder. Sequence: A set of numbers arranged in a specific order. The sequence of even numbers between 50 and 100 is 50, 52, 54, ..., 100. Integer: A whole number that can be positive, negative, or zero. In the context of even numbers, integers are used to express the formula 2n.
