You need to know the least common denominator (LCD) of 9 and 96 if you want to add or subtract two fractions with 9 and 96 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 9 and 96 is 288.
Here is a math problem example where you need to know the LCD of 9 and 96 to solve:
3/9 + 2/96 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
288/9 = 32
288/96 = 3
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 32 = 96
2 x 3 = 6
Step 3) Put it all together to solve the problem:
96/288 + 6/288 = 102/288
= 3/9 + 2/96 = 102/288
It's that easy! Once again, the lowest common denominator (LCD) of 9 and 96 is as follows:
288
