You need to know the least common denominator (LCD) of 35 and 3 if you want to add or subtract two fractions with 35 and 3 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 35 and 3 is 105.
Here is a math problem example where you need to know the LCD of 35 and 3 to solve:
3/35 + 2/3 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
105/35 = 3
105/3 = 35
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 3 = 9
2 x 35 = 70
Step 3) Put it all together to solve the problem:
9/105 + 70/105 = 79/105
= 3/35 + 2/3 = 79/105
It's that easy! Once again, the lowest common denominator (LCD) of 35 and 3 is as follows:
105
