You need to know the least common denominator (LCD) of 6 and 24 if you want to add or subtract two fractions with 6 and 24 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 6 and 24 is 24.
Here is a math problem example where you need to know the LCD of 6 and 24 to solve:
3/6 + 2/24 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
24/6 = 4
24/24 = 1
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 4 = 12
2 x 1 = 2
Step 3) Put it all together to solve the problem:
12/24 + 2/24 = 14/24
= 3/6 + 2/24 = 14/24
It's that easy! Once again, the lowest common denominator (LCD) of 6 and 24 is as follows:
24
