You need to know the least common denominator (LCD) of 92 and 9 if you want to add or subtract two fractions with 92 and 9 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 92 and 9 is 828.
Here is a math problem example where you need to know the LCD of 92 and 9 to solve:
3/92 + 2/9 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
828/92 = 9
