Find the lowest common multiple of the denominators then multiply the top and bottom of the fractions to get this denominator.
so for example for:
1/3 + 1/2 the lowest common multiple is 6.
6 = 3 x 2
so 1/3 = 2x1/2x3 = 2/6
and 1/2 = 3x1/3x2 = 3/6
therefore 1/3 + 1/2 = 2/6 + 3/6 = 2+3/6 = 5/6
and it works for much bigger numbers too

A denominator that is the same in two or more fractions?
A "common denominator"
How do you find the common denominator of 3 fractions?
Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.
How do you put different fractions in increasing order?
Option 1: Find a common denominator for the two fractions. It need not be the least common denominator; for example, for two fractions, if you just multiply the two denominators, you get a common denominator. Convert all the fractions to the common denominator. Then you can compare. Option 2: Convert each fraction to decimal, by dividing the numerator by the denominator. Then you can compare the decimals.
What fraction is bigger seven eighths or nine tenths?

What is the common denominator for 5 over 3?
At least two fractions are needed to determine a common denominator.
What is the least common denominator of two fractions?
The least common denominator is the least common multiple of the denominators of the fractions.
What is the difference between a common denominator and the lowest common denominator?
It is possible for two fractions to have many common denominators. The smallest of these is the LCD.

least common denominator
What is the denominator in the same in two or more fractions?
That's a common denominator.
When two or more fractions have the same denominator it is called what?
Common denominator
What is it called when The denominator is a common multiple of the denominators of two or more fractions?
the least common denominator
What is the least common denominator of 125?
There has to be a set of two or more fractions for a lowest common denominator.
How do you add or subtract dissimilar fractions?
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.
