You need to know the least common denominator (LCD) of 6 and 61 if you want to add or subtract two fractions with 6 and 61 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 6 and 61 is 366.
Here is a math problem example where you need to know the LCD of 6 and 61 to solve:
3/6 + 2/61 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
366/6 = 61
366/61 = 6
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 61 = 183
2 x 6 = 12
Step 3) Put it all together to solve the problem:
183/366 + 12/366 = 195/366
= 3/6 + 2/61 = 195/366
It's that easy! Once again, the lowest common denominator (LCD) of 6 and 61 is as follows:
366
