What is the Least Common Denominator of 5 and 10?


You need to know the least common denominator (LCD) of 5 and 10 if you want to add or subtract two fractions with 5 and 10 as denominators.

The least common denominator, also called lowest common denominator (LCD), of 5 and 10 is 10.


Here is a math problem example where you need to know the LCD of 5 and 10 to solve:

3/5 + 2/10 = ?

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

10/5 = 2
10/10 = 1

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

3 x 2 = 6
2 x 1 = 2

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

6/10 + 2/10 = 8/10
= 3/5 + 2/10 = 8/10

It's that easy! Once again, the lowest common denominator (LCD) of 5 and 10 is as follows:

10
