You need to know the least common denominator (LCD) of 33 and 2 if you want to add or subtract two fractions with 33 and 2 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 33 and 2 is 66.
Here is a math problem example where you need to know the LCD of 33 and 2 to solve:
3/33 + 2/2 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
66/33 = 2
66/2 = 33
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 2 = 6
2 x 33 = 66
Step 3) Put it all together to solve the problem:
6/66 + 66/66 = 72/66
= 3/33 + 2/2 = 72/66
It's that easy! Once again, the lowest common denominator (LCD) of 33 and 2 is as follows:
66
