Not when you multiply or divide fractions, only when you add or subtract fractions. For example, 1/2 x 5/7 = 5/14.
Hope this helps! :)
Find a common denominator (make sure you multiply BOTH the numerator and the denominator) then subtract the numerators and simplify if necessary.
When adding or subtracting fractions with different denominators, it is necessary to find a common denominator to solve the equation. A common denominator is like a common multiple, except its function is as the bottom number in a fraction.
To add fractions with different denominators, first find a common denominator, which is typically the least common multiple (LCM) of the two denominators. Next, convert each fraction to an equivalent fraction with this common denominator by multiplying the numerator and denominator by the necessary factors. Once both fractions have the same denominator, add their numerators together while keeping the common denominator, and simplify the result if possible.

You don't need a common denominator to divide fractions.

fraction having a common denominator
When the numerator is less than the denominator then it is a common fraction but if the numerator is greater than the denominator then it is an improper fraction.
Dividing the numerator and denominator by a common factor is how you simplify a fraction.
You don't need a common denominator to divide fractions.
If a fraction's numerator and denominator have no factors other than one in common, the fraction cannot be simplified except if the denominator is 1, in which case the fraction can be simplified to the whole number of the numerator.
fraction having a common denominator
That's one fraction. You need at least two to find something in common between them.
Multiply the numerator of the fraction by the same amount that you multiply the denominator of that fraction.
If the numerator and denominator of a fraction have a common factor (except for '1'), divide both numerator and denominator by their common factor. The fraction is in the simplest form when the numerator and denominator have no common factors.
