Factors of 2.5
Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing the items equally, arranging things, etc. In this topic, we will learn about the factors of 2.5, how they are used in real life, and the tips to learn them quickly.
What are the Factors of 2.5?
The numbers that divide 2.5 evenly are known as factors of 2.5. A factor of 2.5 is a number that divides the number without remainder. The factors of 2.5 are 1, 2.5, 0.5, and 5. Prime factors of 2.5: 2 and 5. The sum of factors of 2.5: 1 + 2.5 + 0.5 + 5 = 9
How to Find Factors of 2.5?
Factors can be found using different methods. Mentioned below are some commonly used methods: Finding factors using multiplication Finding factors using division method Prime factors
Finding Factors Using Multiplication
To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 2.5. Identifying the numbers which are multiplied to get the number 2.5 is the multiplication method. Step 1: Multiply 2.5 by 1, 2.5 × 1 = 2.5. Step 2: Check for other numbers that give 2.5 after multiplying 0.5 × 5 = 2.5 Therefore, the positive factor pairs of 2.5 are: (1, 2.5) and (0.5, 5).
Finding Factors Using Division Method
Dividing the given numbers with the whole numbers until the remainder becomes zero and listing out the numbers which result as whole numbers as factors. Factors can be calculated by following a simple division method - Step 1: Divide 2.5 by 1, 2.5 ÷ 1 = 2.5. Step 2: Continue dividing 2.5 by the numbers until the remainder becomes 0. 2.5 ÷ 1 = 2.5 2.5 ÷ 0.5 = 5 2.5 ÷ 2.5 = 1 Therefore, the factors of 2.5 are: 1, 2.5, 0.5, and 5.
Prime Factors
The factors can be found by dividing with prime numbers. We can find the prime factors using the following methods: Using prime factorization Using Prime Factorization: In this process, prime factors of 2.5 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1. 2.5 ÷ 0.5 = 5 5 ÷ 5 = 1 The prime factors of 2.5 are 0.5 and 5.
Factor Pairs
Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs. Positive factor pairs of 2.5: (1, 2.5) and (0.5, 5). Negative factor pairs of 2.5: (-1, -2.5) and (-0.5, -5).
Common Mistakes and How to Avoid Them in Factors of 2.5
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
Mistake 1
Forgetting the number itself and 1 is a factor
Children might forget to add the given number itself and 1 as a factor. The number itself and 1 are the factors for every number. Always remember to include 1 and the number itself. For example, in factors of 2.5, 1 and 2.5 are also factors.
Factors of 2.5 Examples
Problem 1
There are 2.5 liters of juice and 5 cups. How will they divide it equally?
Each cup will have 0.5 liters of juice.
Explanation
To divide the juice equally, we need to divide the total juice with the number of cups. 2.5/5 = 0.5
Problem 2
A ribbon is 2.5 meters long. If each piece is to be 0.5 meters, how many pieces will there be?
There will be 5 pieces.
Explanation
To find the number of pieces, we divide the total length by the length of each piece. 2.5/0.5 = 5
Problem 3
A cake weighs 2.5 kg. If each slice is to weigh 0.5 kg, how many slices can you cut?
You can cut 5 slices.
Explanation
To find the number of slices, divide the total weight by the weight of each slice. 2.5/0.5 = 5
Problem 4
You have 5 small boxes, and the total weight of these boxes is 2.5 kg. What is the weight of each box?
Each box weighs 0.5 kg.
Explanation
Dividing the total weight by the number of boxes gives the weight of each box. 2.5/5 = 0.5
Problem 5
A rope is 2.5 meters long, and you have to cut it into 5 equal parts. What is the length of each part?
Each part is 0.5 meters long.
Explanation
To find the length of each part, divide the total length by the number of parts. 2.5/5 = 0.5
