You need to know the least common denominator (LCD) of 36 and 3 if you want to add or subtract two fractions with 36 and 3 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 36 and 3 is 36.
Here is a math problem example where you need to know the LCD of 36 and 3 to solve:
3/36 + 2/3 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
36/36 = 1
36/3 = 12
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 1 = 3
2 x 12 = 24
Step 3) Put it all together to solve the problem:
3/36 + 24/36 = 27/36
= 3/36 + 2/3 = 27/36
It's that easy! Once again, the lowest common denominator (LCD) of 36 and 3 is as follows:
36
