Least Common Denominator of 2 and 11 (LCD of 2 and 11)

Least Common Denominator (LCD) of 2 and 11

The Least Common Denominator of 2 and 11, also known as the Lowest Common Denominator of 2 and 11, is useful if you need to add, subtract, or compare two fractions with the denominators of 2 and 11.

The fractions with 2 and 11 denominators will look like this:

		X
		2

		Y
		11

The Least Common Denominator of 2 and 11 is 22.

You need to multiply 2 by 11 and 11 by 2 to make them both 22. Furthermore, you need to multiply the numerators by the same amounts to keep the fraction values the same.

Therefore, you have to make the following calculations so the fractions keep the same values and get the same denominator:

		X x 11
		2 x 11

		Y x 2
		11 x 2

Which gives you the following two new fractions that you can add, subtract and compare:

		11X
		22

		2Y
		22

You can substitute X and Y with the numerators of your fractions with 2 and 11 denominators. This way you can add, subtract and compare your fractions correctly.
