You need to know the least common denominator (LCD) of 6 and 98 if you want to add or subtract two fractions with 6 and 98 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 6 and 98 is 294.
Here is a math problem example where you need to know the LCD of 6 and 98 to solve:
3/6 + 2/98 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
294/6 = 49
