You need to know the least common denominator (LCD) of 37 and 3 if you want to add or subtract two fractions with 37 and 3 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 37 and 3 is 111.
Here is a math problem example where you need to know the LCD of 37 and 3 to solve:
3/37 + 2/3 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
111/37 = 3
111/3 = 37
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 3 = 9
2 x 37 = 74
Step 3) Put it all together to solve the problem:
9/111 + 74/111 = 83/111
= 3/37 + 2/3 = 83/111
It's that easy! Once again, the lowest common denominator (LCD) of 37 and 3 is as follows:
111
