You need to know the least common denominator (LCD) of 9 and 44 if you want to add or subtract two fractions with 9 and 44 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 9 and 44 is 396.
Here is a math problem example where you need to know the LCD of 9 and 44 to solve:
3/9 + 2/44 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
396/9 = 44
396/44 = 9
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 44 = 132
2 x 9 = 18
Step 3) Put it all together to solve the problem:
132/396 + 18/396 = 150/396
= 3/9 + 2/44 = 150/396
It's that easy! Once again, the lowest common denominator (LCD) of 9 and 44 is as follows:
396
