You need to know the least common denominator (LCD) of 2 and 67 if you want to add or subtract two fractions with 2 and 67 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 2 and 67 is 134.
Here is a math problem example where you need to know the LCD of 2 and 67 to solve:
3/2 + 2/67 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
134/2 = 67
134/67 = 2
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 67 = 201
2 x 2 = 4
Step 3) Put it all together to solve the problem:
201/134 + 4/134 = 205/134
= 3/2 + 2/67 = 205/134
It's that easy! Once again, the lowest common denominator (LCD) of 2 and 67 is as follows:
134
