You need to know the least common denominator (LCD) of 6 and 16 if you want to add or subtract two fractions with 6 and 16 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 6 and 16 is 48.
Here is a math problem example where you need to know the LCD of 6 and 16 to solve:
3/6 + 2/16 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
48/6 = 8
48/16 = 3
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 8 = 24
2 x 3 = 6
Step 3) Put it all together to solve the problem:
24/48 + 6/48 = 30/48
= 3/6 + 2/16 = 30/48
It's that easy! Once again, the lowest common denominator (LCD) of 6 and 16 is as follows:
48
