Multiply any two denominators together. Their product will be a common denominator of them both.
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.
Common denominators are multiples that are being used as denominators. The process to find them is the same.
No.
By finding the lowest common multiple of the different denominators then rearranging the numerators and denominators accordingly.
You can multiply the two denominators, or you can find the least common multiple for the two denominators.
You need at least two denominators to find something in common between them.
By finding the lowest common multiple of the denominators
Multiply them together.
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.
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.
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
You don't. You find a common denominator and proceed from there.
