You need to know the least common denominator (LCD) of 6 and 93 if you want to add or subtract two fractions with 6 and 93 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 6 and 93 is 186.
Here is a math problem example where you need to know the LCD of 6 and 93 to solve:
3/6 + 2/93 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
186/6 = 31
186/93 = 2
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 31 = 93
2 x 2 = 4
Step 3) Put it all together to solve the problem:
93/186 + 4/186 = 97/186
= 3/6 + 2/93 = 97/186
It's that easy! Once again, the lowest common denominator (LCD) of 6 and 93 is as follows:
186
