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. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

Find the lowest common multiple of the denominators and adjust the fractions accordingly

We use the LCM to find the least common denominator of unlike fractions.

least common denominator is nothing but least common multiple of denominators.

When adding unlike fractions, it is necessary to find a common denominator. The process of doing that is the same as finding an LCM.

Addition or subtraction of fractions require "like" fractions: that is, fractions with the same denominator.

-- Find a common denominator. (It will be a number of which all three denominators are factors. The best choice is their least common multiple.) -- Change the fractions to their equivalents with the common denominator. -- Then add their numerators to get the numerator of their sum.

You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.

When comparing fractions you must find a common denominator; by finding the least common denominator it will keep the numbers (numerators and denominator) smaller .

A common denominator. The best way is to find the LCM (Lowest Common Multiple) of all the denominators - the smallest number into which all the denominators will divide. (The easiest way to do this is to multiply all the different denominators together. Once this common denominator has been found, convert all the fractions into equivalent fractions with this new denominator.

Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).

To compare two fractions, find a common denominator, then convert each fraction to equivalent fractions with that common denominator. Finally, you compare the numerators. 5/6

You Ned to find a larger common denominator or multiply the denominators to gain a common denominator.

When adding and subtracting unlike fractions, it is necessary to find the LCM of the denominators, called the least common denominator. Once you have found the LCD, you can convert the fractions to equivalent fractions with a common denominator and proceed with the adding and/or subtracting. Finding an LCM will have no effect on multiplying fractions.

Many places, but a common one is in adding fractions where we find a common denominator.
