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.
you flip the last (second) fraction, and then you change the divide sign into a times sign. You can then times the fractions from there. You do not need the same denominator to times fractions.
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.
To multiply fractions all you do is multiply the numerators and the denominators separately eg: 4/7 x 6/11 = 24/77. The "commonality" of denominators has no relevance.
When dividing fractions, the denominators don't matter. Multiply the first fraction by the reciprocal of the second.

Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.
first you have to find the common denominator and make the 2 fractions denominators the same then you add them and divide them
Dissimilar fractions are fractions that have different denominators.
Dissimilar fractions have different denominators.
The LCD of two fractions is the same as the LCM of their denominators.
You can convert them to equivalent fractions with like denominators, then simply compare the numerators.You might also convert each fraction to a decimal (divide the numerator by the denominator); then you can also compare them.
Multiply or divide both the numeraters and the denominators the same using GCF.Then look at the numeraters. Good luck!!!!!!!
