What is the Least Common Denominator of 3 and 3?




You need to know the least common denominator (LCD) of 3 and 3 if you want to add or subtract two fractions with 3 and 3 as denominators.

The least common denominator, also called lowest common denominator (LCD), of 3 and 3 is 3.


Here is a math problem example where you need to know the LCD of 3 and 3 to solve:

3/3 + 2/3 = ?

Step 1) Take the LCD and divide each denominator by it as follows:

3/3 = 1
3/3 = 1

Step 2) Multiply each nominator with the respective answers from Step 1:

3 x 1 = 3
2 x 1 = 2

Step 3) Put it all together to solve the problem:

3/3 + 2/3 = 5/3
= 3/3 + 2/3 = 5/3

It's that easy! Once again, the lowest common denominator (LCD) of 3 and 3 is as follows:

3
