You need to know the least common denominator (LCD) of 33 and 6 if you want to add or subtract two fractions with 33 and 6 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 33 and 6 is 66.
Here is a math problem example where you need to know the LCD of 33 and 6 to solve:
3/33 + 2/6 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
66/33 = 2
66/6 = 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:
6/66 + 22/66 = 28/66
= 3/33 + 2/6 = 28/66
It's that easy! Once again, the lowest common denominator (LCD) of 33 and 6 is as follows:
66
