You need to know the least common denominator (LCD) of 94 and 4 if you want to add or subtract two fractions with 94 and 4 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 94 and 4 is 188.
Here is a math problem example where you need to know the LCD of 94 and 4 to solve:
3/94 + 2/4 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
188/94 = 2
188/4 = 47
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 2 = 6
2 x 47 = 94
Step 3) Put it all together to solve the problem:
6/188 + 94/188 = 100/188
= 3/94 + 2/4 = 100/188
It's that easy! Once again, the lowest common denominator (LCD) of 94 and 4 is as follows:
188
