You can do it many ways-
1. Multiply the denominators together and then you get your answer.
2. List out the equivalent fractions against each other and then you keep going until you find one that has the same denominator.
3. You use the sock method. For Example: 1/4 and 1/2.four and two are the denominators. 4 and 2 can be divided by 2. 4 divided by 2= 2 and 2 divided by 2= 1. You can't go any farther so you multiply all the numbers. 2,2 and 1. That is 4. (Sorry if this is confusing but its better to do a visual)
Hope the other ones helped though!
What else can I help you with?
What way is subracting fractions with unlike denominators like adding fractions with unlike denominators?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.
How can you find a common denominator for two unlike fractions?
Find the lowest common multiple of the denominators and adjust the fractions accordingly
How do you subtract Fractions with models unlike denominators?
The denominators need to be the same for subtraction. Find the Least Common Denominator for both items and then subtract.
How do you find the common denominator of 3 fractions?
Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.
What is the lowest common multiple of the denominators?
You have to state the denominators to expect an answer

Where to find common denominators?
Multiply any two denominators together. Their product will be a common denominator of them both.
How are common multiple and a common denominator alike and different?
Common denominators are multiples that are being used as denominators. The process to find them is the same.
Do you find common denominators when you multiply fractions?
No.
How do you find the leaset common denominator?
By finding the lowest common multiple of the different denominators then rearranging the numerators and denominators accordingly.
How can you get a dcommon denominator?
You can multiply the two denominators, or you can find the least common multiple for the two denominators.
What is the common denominators of 2 fiths?
You need at least two denominators to find something in common between them.
How do I find a common denominator in a fraction?
By finding the lowest common multiple of the denominators
How do you find a common denominator if the 3 denominators have nothing in common?
Multiply them together.
How is finding the LCM revelant when adding and subtracting fractions?
To add and subtract fractions, you need common denominators. To find the common denominator, find the LCM of the denominators you wish to add or subtract.
How are common multiples and common denominators the same and different?
Common multiples and common denominators can be found using the same process. They differ in their function. Common denominators are common multiples that are functioning as denominators.
When you subtract fractions do you subtract the denominator?
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
