You need to know the least common denominator (LCD) of 6 and 48 if you want to add or subtract two fractions with 6 and 48 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 6 and 48 is 48.
Here is a math problem example where you need to know the LCD of 6 and 48 to solve:
3/6 + 2/48 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
48/6 = 8
48/48 = 1
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 8 = 24
2 x 1 = 2
Step 3) Put it all together to solve the problem:
24/48 + 2/48 = 26/48
= 3/6 + 2/48 = 26/48
It's that easy! Once again, the lowest common denominator (LCD) of 6 and 48 is as follows:
