Yes. You need common denominators if you want to:Add fractionsSubtract fractionsCompare fractions ("which is larger?")You do not need common denominators to multiply or divide fractions. Thus, in the case of fractions, multiplication and division is actually easier than addition and subtraction.

Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.

multiply the 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. To add fractions with unlike denominators, rename the fractions with a common denominator.

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.

first you have to find the common denominator and make the 2 fractions denominators the same then you add them and divide them

The least common denominator is the least common multiple of the denominators of the fractions.

Multiplying the denominators together of two or more unlike fractions will get you a common multiple.
