You need to know the least common denominator (LCD) of 51 and 3 if you want to add or subtract two fractions with 51 and 3 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 51 and 3 is 51.
Here is a math problem example where you need to know the LCD of 51 and 3 to solve:
3/51 + 2/3 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
51/51 = 1
51/3 = 17
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 1 = 3
2 x 17 = 34
Step 3) Put it all together to solve the problem:
3/51 + 34/51 = 37/51
= 3/51 + 2/3 = 37/51
It's that easy! Once again, the lowest common denominator (LCD) of 51 and 3 is as follows:
51
