You need to know the least common denominator (LCD) of 93 and 2 if you want to add or subtract two fractions with 93 and 2 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 93 and 2 is 186.
Here is a math problem example where you need to know the LCD of 93 and 2 to solve:
3/93 + 2/2 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
186/93 = 2
186/2 = 93
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 2 = 6
2 x 93 = 186
Step 3) Put it all together to solve the problem:
6/186 + 186/186 = 192/186
= 3/93 + 2/2 = 192/186
It's that easy! Once again, the lowest common denominator (LCD) of 93 and 2 is as follows:
186
