You need to know the least common denominator (LCD) of 6 and 35 if you want to add or subtract two fractions with 6 and 35 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 6 and 35 is 210.
Here is a math problem example where you need to know the LCD of 6 and 35 to solve:
3/6 + 2/35 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
210/6 = 35
210/35 = 6
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 35 = 105
2 x 6 = 12
Step 3) Put it all together to solve the problem:
105/210 + 12/210 = 117/210
= 3/6 + 2/35 = 117/210
It's that easy! Once again, the lowest common denominator (LCD) of 6 and 35 is as follows:
210
