You need to know the least common denominator (LCD) of 14 and 16 if you want to add or subtract two fractions with 14 and 16 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 14 and 16 is 112.
Here is a math problem example where you need to know the LCD of 14 and 16 to solve:
3/14 + 2/16 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
112/14 = 8
112/16 = 7
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 8 = 24
2 x 7 = 14
Step 3) Put it all together to solve the problem:
24/112 + 14/112 = 38/112
= 3/14 + 2/16 = 38/112
It's that easy! Once again, the lowest common denominator (LCD) of 14 and 16 is as follows:
112
