You need to know the least common denominator (LCD) of 7 and 95 if you want to add or subtract two fractions with 7 and 95 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 7 and 95 is 665.
Here is a math problem example where you need to know the LCD of 7 and 95 to solve:
3/7 + 2/95 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
665/7 = 95
665/95 = 7
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 95 = 285
2 x 7 = 14
Step 3) Put it all together to solve the problem:
285/665 + 14/665 = 299/665
= 3/7 + 2/95 = 299/665
It's that easy! Once again, the lowest common denominator (LCD) of 7 and 95 is as follows:
665
