You need to know the least common denominator (LCD) of 5 and 94 if you want to add or subtract two fractions with 5 and 94 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 5 and 94 is 470.
Here is a math problem example where you need to know the LCD of 5 and 94 to solve:
3/5 + 2/94 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
470/5 = 94
470/94 = 5
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 94 = 282
2 x 5 = 10
Step 3) Put it all together to solve the problem:
282/470 + 10/470 = 292/470
= 3/5 + 2/94 = 292/470
It's that easy! Once again, the lowest common denominator (LCD) of 5 and 94 is as follows:
470
