You need to know the least common denominator (LCD) of 2 and 37 if you want to add or subtract two fractions with 2 and 37 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 2 and 37 is 74.
Here is a math problem example where you need to know the LCD of 2 and 37 to solve:
3/2 + 2/37 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
74/2 = 37
74/37 = 2
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 37 = 111
2 x 2 = 4
Step 3) Put it all together to solve the problem:
111/74 + 4/74 = 115/74
= 3/2 + 2/37 = 115/74
It's that easy! Once again, the lowest common denominator (LCD) of 2 and 37 is as follows:
74
