![]() ![]() In the next step, we have to find the L.C.M (Least common multiple) of 2, 3 and 5. If we have more than two fractions, we can use only L.C.M method. In this problem, we have more than two fractions. The denominators of all the fractions are not same. So, the sum of the two fractions is 41/63. When we do the above three steps, we will have Multiply the denominators of the two fractions. Multiply the numerator of the second fraction by denominator of the first fraction. Multiply the numerator of the first fraction by denominator of the second fraction. To add the two fractions, we have to do the following three steps. Here, we have to apply cross multiplication method to add the two fractions. So, the sum of the two fractions is 23/60.įor 7 and 9, there is no common divisor other than 1. To make the denominator to be 60, we have to multiply the numerator and denominator of the first fraction by 3 and and for the second fraction by 2. Now we have to make the denominators of both the fractions to be 60. ![]() In the next step, we have to find the L.C.M (Least common multiple) of 20 and 30. So, the sum of the two fractions is 5/36.įor 20 and 30, we have the following common divisors other than 1. To make the denominator to be 36, we have to multiply the numerator and denominator of the first fraction by 3 and the second one by 2. Now, make the denominators of both the fractions to be 36. In the next step, we have to find the LCM (Least common multiple) of 12 and 18. Because, they have different denominators.įor 12 and 18, we have the following common divisors other than 1. This process is summarized in Figure 03 below.The given two fractions are unlike fractions. ![]() Since 3/4 can not be simplified further, you can conclude that… To complete this first example, simply add the numerators together and express the result as one single fraction with the same denominator as follows: Since the denominators are the same, you can move onto Step Three. Step One: Identify whether the denominators are the same or different.Ĭlearly, the denominators are the same since they both equal 4 Okay, let’s take our first attempt at using these steps to solve the first example: 1/4 + 2/4 = ? Step Three: Add the numerators and find the sum. If they are different, find a common denominator. Step Two: If they are the same, move onto Step Three. Step One: Identify whether the denominators are the same or different Our first example is rather simple, but it is perfect for learning how to use our easy 3-step process, which you can use to solve any problem that involves adding fractions: How to Add Fractions with Like Denominators How to Add Fractions with Like Denominators: Example #1 How to add fractions with different denominators?īut, before you learn how to add fractions, lets do a quick review of some key characteristics and vocabulary terms related to fractions before we move onto a few step-by-step examples of how to add fractions. How to add fractions with the same denominator? What is the difference between the numerator and denominator of a fraction? This guide will teach you the following skills (examples included): The free free How to Add Fractions Step-by-Step Guide will teach you how to add fractions when the denominators are the same and how to add fractions with different denominators using a simple and easy 3-step process. ![]() Luckily, learning how to add fractions with like and unlike (different) denominators is a relatively simple process. (Looking to learn how to subtract fractions?
