You need to know the least common denominator (LCD) of 37 and 9 if you want to add or subtract two fractions with 37 and 9 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 37 and 9 is 333.
Here is a math problem example where you need to know the LCD of 37 and 9 to solve:
3/37 + 2/9 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
333/37 = 9
333/9 = 37
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 9 = 27
2 x 37 = 74
Step 3) Put it all together to solve the problem:
27/333 + 74/333 = 101/333
= 3/37 + 2/9 = 101/333
It's that easy! Once again, the lowest common denominator (LCD) of 37 and 9 is as follows:
333
