You need to know the least common denominator (LCD) of 67 and 3 if you want to add or subtract two fractions with 67 and 3 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 67 and 3 is 201.
Here is a math problem example where you need to know the LCD of 67 and 3 to solve:
3/67 + 2/3 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
201/67 = 3
201/3 = 67
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 3 = 9
2 x 67 = 134
Step 3) Put it all together to solve the problem:
9/201 + 134/201 = 143/201
= 3/67 + 2/3 = 143/201
It's that easy! Once again, the lowest common denominator (LCD) of 67 and 3 is as follows:
201
