Lesson 2: Common denominators

# Common denominators: 1/4 and 5/6

Learn how to find common denominators for fractions with different numerators and denominators by identifying multiples of the original denominators. It demonstrates the process using 1/4 and 5/6, showing that 12 and 24 can be common denominators.

• why do they change the person why is speaking every time
• I think because one person was to busy so they take turns i think yeah.

• Are LCM and LCD the same? I know the process for getting them IS the same, but I don't know whether they ARE the same. I know it sounds weird, but are they the same?
• They could be the same, depending on what LCD is.

LCM stands for Lowest Common Multiple. That's the smallest multiple that can divide every number in a set of numbers.

LCD could stand for Lowest Common Denominator, which would make it a type of LCM, and is just what we use in fraction LCM.

LCD could also be Lowest Common Divisor, which is exactly the same as LCM.
