You need to know the least common denominator (LCD) of 93 and 80 if you want to add or subtract two fractions with 93 and 80 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 93 and 80 is 7440.
Here is a math problem example where you need to know the LCD of 93 and 80 to solve:
3/93 + 2/80 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
7440/93 = 80
7440/80 = 93
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 80 = 240
2 x 93 = 186
Step 3) Put it all together to solve the problem:
240/7440 + 186/7440 = 426/7440
= 3/93 + 2/80 = 426/7440
It's that easy! Once again, the lowest common denominator (LCD) of 93 and 80 is as follows:
7440
