You need to know the least common denominator (LCD) of 11 and 2 if you want to add or subtract two fractions with 11 and 2 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 11 and 2 is 22.
Here is a math problem example where you need to know the LCD of 11 and 2 to solve:
3/11 + 2/2 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
22/11 = 2
22/2 = 11
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 2 = 6
2 x 11 = 22
Step 3) Put it all together to solve the problem:
6/22 + 22/22 = 28/22
= 3/11 + 2/2 = 28/22
It's that easy! Once again, the lowest common denominator (LCD) of 11 and 2 is as follows:
22
