How to add fractions with a common denominator?
Fractions are composed of a numerator and denominator, and when two fractions have the same number for a denominator, it is known as a common, or like, denominator. Adding fractions together when they have a common denominator is easy to do, because you can just add all the numerators together! The new fraction will use the same original denominator, so all you have to worry about is adding the numbers above the line. The same is true for subtracting fractions that have common denominators. Things get a little trickier when the fractions don’t have the same denominator, but they can still be added or subtracted by finding a common denominator first.
How to add fractions?
1. Locate the denominators. Fractions don’t always have the same denominators, and in order to add or subtract those fractions, you must first find a common denominator. To start, locate the denominators in the fractions you’re dealing with. For instance, in the equation 5/8 + 6/9, the denominators are 8 and 9.
How to convert an improper fraction to a mixed number?
To convert an improper fraction like 25/8 to a mixed number, you: Divide the improper fraction’s numerator by its denominator to determine how many whole times 8 goes into 25, where the answer is 25 ÷ 8 = 3 (.125) Determine what’s left over.
What happens when you rewrite a fraction?
Rewrite the fractions. The new fraction will have the common denominator and the product of the numerators multiplied by the same values:
What is improper fraction?
Convert improper fractions to mixed numbers if necessary. When a fraction has a numerator that’s bigger than the denominator, such as 25/8 , this is said to be an improper fraction (the reverse, when the numerator is smaller than the denominator, is a proper fraction).
How to get the least common multiple?
Multiply the fractions to achieve the least common multiple. Multiply each denominator by the correct number to achieve the common denominator . Remember that whatever you do to each denominator, you must also do to its numerator. For the fraction 5/8: to achieve the common denominator of 72, you multiply 8 x 9.
How to convert fractions to decimals?
Any fraction can be converted from a fraction by dividing the numerator by the denominator, and you’ll often end up with a decimal number . For instance, 5/8 can also be written as 5 ÷ 8, which equals 0.625.
How to add fractions with different denominators?
The fractions with different denominators can be added by making the denominators common . This is possible by multiplying the numerator and denominator of each of the fractions with a suitable constant. To add the fractions 3/5 + 4/3, we need to multiply both the fractions with a number which makes the denominators equal. For this, we need the LCM of the denominators, which is 15 in this case. The numerator and denominator of the first fraction 3/5 have to be multiplied by 3, and the numerator and denominator of the second fraction 4/3 have to be multiplied by 5. Hence, we have (3/5 × 3/3) + (4/3 × 5/5) = (9/15) + (20/15) = (9 + 20)/15 = 29/15.
How to Add Fractions?
Before moving to the addition of fractions, let us quickly revise what are fractions. Fractions are made up of two parts, the numerator, and the denominator. A general representation of a fraction is a/b, where a is the numerator, 'b' is the denominator, and b cannot be zero. Some of the examples of fractions are 2/3, 14/5, 6/7, 28/9, 21/43. Just like other numbers, we can perform the arithmetic operations of addition, subtraction, multiplication, and division on fractions. The addition of fractions means finding the sum of two or more fractions. Now, let us learn the basic steps of the addition of fractions which are given below with the help of an example of adding 1/4 + 2/4.
What is the basic rule for adding fractions?
The basic rule for the addition of fractions is to make the denominators of the fractions the same. Only then we can add fractions.
Why do we use fractions?
Fractions are used to represent a part of a whole and they show a way to split a number into equal parts. The addition of fractions is a little different from the normal addition of numbers since a fraction has a numerator and a denominator which is separated by a bar. The main aim is to make the denominators equal, and then the addition can be carried out easily. While like fractions have common denominators, unlike fractions are converted to like fractions to make addition easier. Let us explore more about the addition of fractions in this lesson.
How to solve mixed fractions?
Mixed fractions can be solved by converting them into improper fractions. This can be done by multiplying the denominator with the whole number and then adding the numerator to it. Let us convert a mixed fraction 3½ into an improper fraction. 3½ = { (2 × 3) + 1} /2= (6 + 1)/2 = 7/2.
How to make 3 and 5 like fractions?
LCM of 3 and 5 = 15. Step 2: Now, multiply 1/3 with 5/5, (1/3) × (5/5) = 5/15, and 3/5 with 3/3, (3/5) × (3/3) = 9/15 which will convert them to like fractions with the same denominators.
How to add whole numbers and fractions?
An easy way to add a whole number and fraction is to write the given fraction in its mixed form. 5 + 1/2 = 5½ = 11/2, 3 + 1/7 = 31 7 3 1 7 = 22/7. Let us look at another method for adding fractions with whole numbers.
How to tell if fractions have the same denominator?
Check the denominators (bottom numbers) of each fraction. If they are the same number, then you're dealing with fractions that have the same denominator. If not, skip to the section down below.
How to simplify a fraction?
Simplify by dividing both the numerator and the denominator in the fraction by each number's greatest common factor. Ex. 3: 14/15 cannot be simplified. Ex. 4: 6/14 can be reduced to 3/7 by dividing both the top and the bottom numbers by 2, the greatest common factor.
What fractions are like apples and oranges?
Adding fractions with unlike denominators would be like adding apples and oranges. Adding 1/4 and 2/3 is similar to trying to add one apple and two oranges. You would have three... but three what? If you called each apple and each orange a "piece of fruit," then you could add them together. So if we convert both 1/4 and 2/3 into twelfths, you could add them together as twelfths. 1/4 is 3/12, and 2/3 is 8/12. Adding them together gives us 11/12.
Why don't we multiply the second fraction?
Ex. 4: We don't need to multiply the second fraction because both fractions already have their common denominators.
What is the top number of a fraction?
Add together the numerators of the two fractions. The numerator is the top number of the fraction.
What is the numerator of a fraction?
The numerator is the number on top of the fraction. However many fractions you have, if they have the same bottom numbers, add up all the top numbers. Ex. 1: 1/4 + 2/4 is our equation. "1" and "2" are the numerators. That means 1 + 2 = 3. Ex. 2: 3/8 + 2/8 + 4/8 is our equation. "3" and "2" and "4" are the numerators.
How to find the unlike denominator?
1. Check the denominators (bottom numbers) of each fraction. If the denominators are different numbers, then you're dealing with unlike denominators. You're going to have to find a way to make the unlike denominators be the same.
How to make the denominators the same?
