You need to know the least common denominator (LCD) of 95 and 84 if you want to add or subtract two fractions with 95 and 84 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 95 and 84 is 7980.
Here is a math problem example where you need to know the LCD of 95 and 84 to solve:
3/95 + 2/84 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
7980/95 = 84
7980/84 = 95
