You need to know the least common denominator (LCD) of 52 and 9 if you want to add or subtract two fractions with 52 and 9 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 52 and 9 is 468.
Here is a math problem example where you need to know the LCD of 52 and 9 to solve:
3/52 + 2/9 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
468/52 = 9
468/9 = 52
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 9 = 27
2 x 52 = 104
Step 3) Put it all together to solve the problem:
27/468 + 104/468 = 131/468
= 3/52 + 2/9 = 131/468
It's that easy! Once again, the lowest common denominator (LCD) of 52 and 9 is as follows:
468
