To find the common denominator of two fractions, you find the least common multiple of the denominators. The multiply the numerators by whatever you multiplied the denominator by to get an equivalent fraction.
example:
1 + 2 = 10
3 4 12
the least common multiple of 3 and 4 is 12 so,
4 + 6 = 10
12 12 12 which can be reduced to the answer of 5

How do you subtract fractions when denominator is different?
By finding the lowest common denominator of the fractions.
What is the rule of adding and subtracting different denominator?
Find the lowest common denominator by finding the lowest common multiple of the denominators
Is it always necessary to find the least common denominator to compare the sizes of fractions?
When comparing fractions you must find a common denominator; by finding the least common denominator it will keep the numbers (numerators and denominator) smaller .
How do you add a dissimilar fraction?
By finding their lowest common denominator
How do you subtract fractions with unequal denominators?
by finding the common denominator of the fractions
What do you call a process of finding the factors of the given products?
finding the least common denominator formula
Why might it be important to know to calculate least common multiples?
The process of finding the LCM is the same as finding the least common denominator which is important when you want to add and subtract fractions.

When multiplying fractions the shortcut process of finding common factors that divide evenly into at least one of the numerator and one of the denominator is called?
It is called simplification [by cancelling common factors].
What is the common denononator?
In fractions, the denominator is the bottom number. When adding or subtracting fractions, it is helpful if all the denominators are the same. To do this, we look for common denominators, which is the same process as finding the least common multiple.
