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

Least Common Denominator (LCD) of 11 and 2

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

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

		X
		11

		Y
		2

The Least Common Denominator of 11 and 2 is 22.

You need to multiply 11 by 2 and 2 by 11 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 2
		11 x 2

		Y x 11
		2 x 11

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

		2X
		22

		11Y
		22

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