Learn how to add or subtract fractions by finding a common denominator. See examples, definitions and explanations of denominators and common denominators.
A common denominator is a denominator that you can reach by both denominators. For example in the problem 3/4+ 5/6 a common denominator is 12 because it is the lowest number that both 4 and 6 can reach by multiplying with whole numbers.

- How do I find LCM with 3 fractionsIts quite simple you find out what the three numbers are, lets say the numbers are: 2,3,4. then you wright the numbers they all have in common. 2:...
- What if one of the denominators is a 1?If the denominator is a 1, then it's still the same formula: you simply divide the denominator by the numerator (ex: 4/1 = 4 divided by 1 = 4). It...
- Can someone explane this to me pls?So you have to find a common denominator, right? For this one, you have to multiply to get the common denominator. So what times 6 equals 24? Also,...
- is LCM n LCD are same?The LCM is used to find the LCD but yes they are the same
- is LCM n LCD are same ?Yes, you can think of them somewhat interchangeably. The LCD for any 2 fractions is the LCM for their denominators. However, LCM is used for other...
- How to know if you are finding the common denominators with some choices like; 3/4+1/3 A.3/4+1/3 = 9...The key is to remember that if you multiply the denominator by a value, you also have to multiply the numerator by that same value. In this example...
Learn how to find and use common denominators for fractions, and practice with examples and exercises. Common denominators make it easier to compare, add, and subtract fractions.
- At first I was really confused with the least common denominator Q's. Then i realised that I had to ...At first i was confused by the option 15 because i wasn't thinking straight and thought that 15 was 10 times five instead of 10 plus five :)
- How do you find a common denomenator for 2 fractions like 1/5 and 2/6?You would just keep listing all the multiples until you find a common one, so both 5 and 6 are multiples of 30, so the common denominator would be 30
- That was sorta hard but funCan you up vote this
- the lowest common denominater of 1/6 and 3/6 is 12 right?No, in this case 1/6 and 3/6 already have a common denominator of 6.
- What's 1/4 plus 11/10?1∕4 + 11∕10 First, let's find the least common denominator. One way of doing this is to write down multiples of the smaller denominator until we ge...
- how do you find the common denominators?Usually multiple the denominators then cross multiply the denominators by the numerators.So if you have 4/6 x 5/8= what you would do is do 8 x 6 an...
- Are two fractions multiplied equals 1 called reciprocals?Reciprocals are fractions turned upside down and have the numerator in the denominator area with the denominator in the numerator area. For example...
