You need to know the least common denominator (LCD) of 1 and 93 if you want to add or subtract two fractions with 1 and 93 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 1 and 93 is 93.
Here is a math problem example where you need to know the LCD of 1 and 93 to solve:
3/1 + 2/93 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
93/1 = 93
93/93 = 1
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 93 = 279
2 x 1 = 2
Step 3) Put it all together to solve the problem:
279/93 + 2/93 = 281/93
= 3/1 + 2/93 = 281/93
It's that easy! Once again, the lowest common denominator (LCD) of 1 and 93 is as follows:
93
